Description

Technical Field

[0001] The present invention relates to the field of satellite communication and satellite navigation, and in particular to a satellite communication and navigation symbiosis system, and also to a method for realizing satellite communication and navigation symbiosis. The system utilizes the relationship between a satellite communication system and a satellite navigation system to provide a more reliable, efficient and comprehensive wireless communication and navigation solution. Background Art

[0002] Traditionally, satellite communications and satellite navigation systems have been viewed as separate technology areas, used to provide wireless communications and global positioning navigation services, respectively. However, there are potential synergies between the two systems in some application scenarios. For example, in disaster relief and emergency situations, both communication and positioning information need to be obtained simultaneously. However, since these systems are usually independent, there may be problems with communication interruptions or inaccurate positioning.

[0003] Traditional "communication and navigation integrated" technology may have the following disadvantages:

[0004] 1. Limited performance: In traditional "communication and navigation integrated" technology, communication and navigation functions are usually combined in one system, which may lead to limited performance. Because the two functions share resources, conflicts may occur, resulting in reduced communication quality or reduced navigation accuracy.

[0005] 2. Communication and navigation cannot be optimized independently: In traditional technologies, communication and navigation functions cannot usually be optimized independently. This means that in some cases, one function needs to be sacrificed to meet the needs of another function, and it is impossible to strike a balance between the two.

[0006] 3. Lack of adaptability: Traditional technologies may not be flexible enough to adapt to different application scenarios and needs. Usually, this technology lacks real-time status monitoring and automatic adjustment functions, and cannot make adaptive adjustments according to environmental changes.

[0007] 4. System complexity: Merging communication and navigation functions may increase system complexity. This will increase the difficulty of maintenance and management and may lead to more failures and problems.

[0008] 5. Low resource utilization efficiency: In traditional technologies, communication and navigation functions share resources, which may lead to inefficient resource utilization. In some cases, resource waste or unnecessary conflicts may occur.

[0009] To sum up, the reason why traditional "communication and navigation integrated" technology has these shortcomings is mainly because it has not established a close collaborative relationship, cannot achieve independent optimization of communication and navigation functions, and lacks flexibility and real-time performance, so it is limited in responding to different application requirements and environmental changes.

[0010] Therefore, a new technical solution is needed to achieve symbiosis between satellite communication and satellite navigation systems to provide more powerful and reliable communication and navigation capabilities. Summary of the invention

[0080] The following are the sensors and monitoring devices in a satellite communication system or satellite navigation system, and the values ​​they monitor:

[0081] Sensors and monitoring equipment:

[0082] a. Inertial Measurement Unit (IMU):

[0083] Monitoring values: acceleration, angular velocity, attitude (heading, pitch, roll angle).

[0095] Monitoring values: signal strength, signal-to-noise ratio, signal delay.

[0096] Purpose: Used to monitor the quality of satellite communication signals and help optimize communication performance.

[0097] Optimization steps:

[0098] a. Real-time data collection: Use the above sensors and monitoring equipment to collect satellite status information in real time, including attitude, position, temperature, communication signal quality and other data.

[0099] b. Data analysis and processing: Analyze the collected data to identify any abnormal or unstable patterns so that timely measures can be taken.

In actual applications, the specific sensors, monitoring equipment and optimization steps may vary depending on project requirements.

[0104] Through the symbiotic control module, the satellite communication system uses the navigation function to improve the communication capacity; the satellite navigation system uses the communication function to improve the positioning accuracy.

[0105] Satellite communication systems use navigation functions to increase communication capacity:

[0106] Navigation can help improve the capacity and efficiency of satellite communication systems. In wireless communications, especially in mobile communication systems, signals may be affected by multipath propagation, signal interference and other issues. By using satellite navigation systems, such as global satellite navigation systems (such as GPS, GLONASS, etc.), communication devices can determine their own positions more accurately. When communication devices know their positions, they can adjust signal transmission and reception parameters based on the current position information, thereby optimizing the quality of the communication link and improving the communication capacity. This optimization can include selecting the best channel, adjusting power levels, reducing interference, etc.

[0107] Satellite navigation systems use communication functions to improve positioning accuracy:

[0108] Communication capabilities can help improve the positioning accuracy of satellite navigation systems. Satellite navigation systems typically use satellite signals to determine the location of the receiving device. However, in some cases, such as in urban canyons and between tall buildings, satellite signals may be blocked, resulting in reduced positioning accuracy. Satellite navigation systems can use communication signals to improve positioning accuracy. For example, by analyzing the propagation characteristics of received mobile communication signals, satellite navigation systems can more accurately estimate the location of a device, especially in places where satellite signals are not strong enough. This technology is called Assisted GPS (A-GPS), which improves the speed and accuracy of GPS positioning by interacting with mobile communication networks.

[0109] In summary, the communication and navigation functions support each other and can jointly improve the performance and accuracy of their respective systems.

[0110] In terms of physical structure, the two can share system resources such as signal processing, modulation and demodulation, and these shared resources can be incorporated into the structure of the symbiont.

[0111] The implementation details of the satellite communication system are as follows:

[0112] Satellite communication equipment selection: Select satellite communication equipment suitable for different communication needs, including transmitters and receivers in different frequency bands, antenna systems, etc.

[0113] Communication protocol and modulation: Define the communication protocol and modulation to ensure stable transmission of communication signals between satellites and between satellites and ground equipment. For example, use frequency modulation or phase modulation modulation and select appropriate error correction coding.

[0114] Signal transmission and processing: Satellite communication equipment is responsible for converting data into appropriate communication signals and transmitting them to the target satellite or ground equipment. The receiver is responsible for receiving, decoding and processing the transmitted signals.

[0115] Satellite communication systems can use different frequency bands and modulation methods to meet different communication needs.

[0116] The implementation details of the satellite navigation system are as follows:

[0117] Positioning Satellite Deployment: A group of positioning satellites are deployed, which operate in different orbits to provide global coverage. These satellites transmit positioning signals containing data about the satellite's own position and time information.

[0118] Receiver and positioning algorithm: A satellite communication receiver is used to receive signals from positioning satellites and use positioning algorithms to calculate the user's precise location. Common positioning algorithms include differential positioning, weighted least squares, etc.

[0119] The implementation details of the symbiosis control module are as follows:

[0120] Condition monitoring: Deploy sensors and monitoring equipment to monitor various aspects of satellite communication systems and satellite navigation systems, including signal strength, communication quality, satellite position, etc.

[0121] Intelligent decision-making: Based on monitoring data and preset strategies, the symbiotic control module can make intelligent decisions, such as selecting the best communication frequency band, adjusting signal transmission power to optimize communication quality, or adjusting positioning algorithms to improve navigation accuracy.

[0122] The implementation details of the data exchange interface are as follows:

[0123] Data format and protocol: Determine the format of shared data and the communication protocol to ensure smooth communication. Standard data formats such as JSON or XML can be used to facilitate parsing and processing of information.

[0124] Real-time exchange: In the communication and navigation symbiosis system, the data exchange mechanism refers to the methods and rules used to achieve real-time data exchange between different elements. These mechanisms usually need to be designed to ensure the security, accuracy and real-time nature of the data. Design the corresponding data exchange mechanism to achieve real-time data exchange. This can be achieved through wireless or wired connections, depending on the application scenario and system design.

[0125] Through the above module implementation details, the satellite communication and navigation symbiotic system can achieve close cooperation between the satellite communication system and the satellite navigation system, thereby providing more optimized communication and navigation performance. This symbiotic system can play an important role in different application fields, such as traffic navigation, emergency rescue, etc.

[0126] In the present invention, Figure 2 The figure shows the implementation structure of the symbiotic control module. The symbiotic control module is the core component of the satellite communication and navigation symbiotic system, responsible for achieving close coordination and optimization between the satellite communication system and the satellite navigation system to provide more reliable, efficient and comprehensive wireless communication and navigation solutions. The detailed description of the design and function of the symbiotic control module includes the following aspects:

[0127] 1. Status monitoring and data acquisition: The symbiotic control module monitors the status of the satellite communication system and the satellite navigation system in real time by deploying various sensors and monitoring devices. These sensors and monitoring devices may include signal strength sensors, communication quality assessment modules, positioning accuracy measurement devices, etc. These devices regularly report data about communication link quality, navigation accuracy, satellite position, etc. to the symbiotic control module. Through continuous data acquisition, the symbiotic control module is able to obtain a comprehensive picture of system performance. It should be noted that the communication and navigation symbiotic system is a broad concept that can be applied to a variety of different fields, including the Internet of Things, smart cities, and traffic management. In different application scenarios, the required communication quality assessment modules, signal strength sensors, and positioning accuracy measurement devices may be different. There are no specific standards or fixed regulations for the selection of specific models, manufacturers, and specific equipment in the communication and navigation symbiotic system. For example, general satellite communications use the onboard 5G / 6G standard, and satellite navigation uses GPS or Beidou standard. The corresponding equipment model can be selected according to the standard.

[0128] 2. Data analysis and decision making: The symbiotic control module receives real-time data from sensors and monitoring equipment and performs data analysis to understand the current status of the satellite communication system and satellite navigation system. By analyzing the data, the symbiotic control module is able to identify potential problems, bottlenecks and opportunities. Based on these analysis results, intelligent decisions are made to optimize the performance of the entire system.

[0129] 3. Intelligent adjustment and optimization: Based on the results of data analysis, the symbiotic control module can intelligently adjust the various parameters of the satellite communication system and the satellite navigation system to optimize the performance of the system. For example, in terms of communication, the symbiotic control module can adjust the signal transmission power, select the appropriate communication frequency band, or adjust the modulation method according to the quality of the communication link. In terms of navigation, the parameters of the positioning algorithm can be adjusted according to the requirements of positioning accuracy, or the navigation results can be optimized according to the changes in the satellite position.

[0130] 4. Backup and switch: The symbiotic control module has the function of backup and switch in the event of system failure or interference. If there is a problem with the satellite communication system or the satellite navigation system, the symbiotic control module can automatically switch to the backup solution to ensure the continuity and reliability of the system. For example, when the communication signal quality decreases, the symbiotic control module can switch to the backup satellite communication link to maintain the stability of communication.

[0131] 5. User demand response: The symbiotic control module can also make adjustments based on user needs. For example, in a disaster relief scenario, users may have special requirements for positioning accuracy and communication reliability. The symbiotic control module can optimize the operation of the system based on these special requirements to meet the actual needs of users.

[0132] 6. Human intervention and supervision: Although the symbiotic control module has intelligent autonomous decision-making capabilities, it also allows human intervention and supervision. System administrators or operators can interact with the symbiotic control module through the interface to perform manual adjustments, policy formulation, or troubleshooting.

[0133] In summary, the symbiotic control module is the intelligent core of the satellite communication and navigation symbiotic system. It achieves close coordination between the satellite communication system and the satellite navigation system through real-time data analysis, intelligent decision-making, parameter adjustment, and backup switching to achieve optimal performance and reliability. The symbiotic control module can adapt to different needs in different application scenarios and provide users with higher quality services.

[0134] In the present invention, the data exchange interface is a key part that connects the satellite communication system and the satellite navigation system in the satellite communication and navigation symbiosis system. It allows the two systems to transfer, communicate and share information, thereby achieving closer collaboration and coordination. The following is a detailed description of the data exchange interface, including hardware connection, message transmission and protocol description. In the satellite communication and navigation symbiosis system, the data exchange interface is responsible for transmitting information and instructions to achieve efficient communication between the satellite communication system and the satellite navigation system. This key part must ensure the security and reliability of the data while ensuring the collaborative work between the various modules within the system. The data exchange interface is not only a channel for information transmission, but also needs to have the ability to detect and correct errors to cope with various interferences and noises that may be encountered during the satellite communication and navigation process.

[0135] In addition, the design and performance of the data exchange interface directly affect the stability and performance of the entire satellite communication and navigation system. An efficient and reliable data exchange interface can improve the system's response speed, reduce communication latency, and provide more accurate and reliable navigation services. Therefore, in the design and development of satellite communication and navigation systems, the optimization and improvement of the data exchange interface is a crucial task and a key step in improving the overall system performance.

[0136] (1) Hardware connection: The data exchange interface needs to establish a physical connection to ensure the reliability and stability of communication. This can be achieved through wireless connection between satellites or wired connection between satellites and ground equipment, depending on the application scenario and system design.

[0137] Wireless connection: Data exchange between satellites can be carried out using wireless communication technologies, such as radio frequency communication. Data between the satellite communication system and the satellite navigation system can be transmitted through wireless signals, which can make use of existing communication frequency bands and communication links between satellites. In satellite communication systems, data transmission between the satellite communication system and the satellite navigation system is usually carried out through wireless signals. This wireless data transmission can be carried out with the help of different communication technologies, such as radio waves, microwaves or laser communications, to ensure efficient data transmission. By using existing communication frequency bands and communication links between satellites, fast and stable data transmission can be achieved without the need to build new dedicated communication infrastructure, saving costs and resources.

[0138] Wired connection: Due to the requirements of security and stability, it is possible to establish a wired connection between the ground equipment of the satellite core network. This can be achieved through physical media such as optical fiber and cable. Figure 2 The figure shows the data exchange interface module structure.

[0139] Among the four parts of the communication and navigation symbiosis system, the satellite communication system, satellite navigation system, symbiosis control module, and data exchange interface are not required to be in the same physical device. They can be deployed in a distributed manner to facilitate the use of existing equipment and expansion and upgrading.

[0140] (41) The satellite has both communication and navigation functions, and its data exchange interface (411) is divided into two parts: the internal interface is responsible for the information exchange between the communication component, navigation component, and communication and navigation symbiotic control module within the satellite. The external information interface is responsible for the communication connection between the satellite (or this type) and the ground equipment (satellite terminal or ground station).

[0141] (42) is a satellite with only communication function, which is connected to the ground through the on-board data exchange interface (421), and the positioning information of the navigation satellite is obtained by ground commands to improve the communication quality. In this system, the on-board data exchange interface allows the satellite to communicate with the ground station. Through the commands sent by the ground station, the satellite can obtain the positioning information of the navigation satellite. This information exchange process is crucial to improving the communication quality. The on-board data exchange interface is a hardware or software component on the satellite that allows the satellite to exchange data with other satellites, ground stations or other space and ground equipment. This interface usually uses wireless communication technology, such as radio waves or laser communications, to connect with ground stations or other satellites.

[0142] (43) is a satellite with only navigation function, which is connected to the ground communication through the on-board data exchange interface (431), obtains the resources of the communication satellite through ground commands, and improves the navigation positioning accuracy.

[0143] Satellites with only navigation functions communicate with ground stations through onboard data exchange interfaces and obtain the resources of communication satellites through ground commands to improve their own navigation and positioning accuracy.

[0144] First, these satellites are connected to the ground through the onboard data exchange interface, that is, the communication equipment on the satellite. This connection is usually based on wireless communication technology, allowing the satellite to exchange data and transmit commands with the ground station.

[0145] Secondly, through ground commands, satellites can obtain resources from communication satellites. These resources may include positioning data of communication satellites, precise clock information, antenna pointing information, etc. Communication satellites are usually equipped with more communication equipment and precise positioning systems, so they can provide more accurate resource data. By receiving commands sent by ground stations, satellites can obtain these resource data to improve their own navigation and positioning performance.

[0146] Finally, navigation-only satellites can improve their navigation positioning accuracy by acquiring resources from communications satellites. This resource data can be used to calibrate the satellite's internal systems, helping the satellite to more accurately determine its own position, speed, and time. This is critical for navigation systems because accurate positioning information can help users accurately locate anywhere on Earth, whether on land, sea, or in the air.

[0147] (44) is a ground data exchange interface, which can be arranged in a ground terminal, a ground relay base station or a ground station. On the one hand, it exchanges data with the satellite, and on the other hand, it interacts with the communication and navigation symbiosis cloud platform (45) of the ground network control center. The control module of the communication and navigation symbiosis can be deployed on the cloud of the ground network, and the large-scale computing and storage parts are all placed on the ground cloud platform. Different types of constellations on the satellite cooperate with each other according to the instructions sent upward by the data interface to enhance the communication and navigation performance of the network. The communication and navigation symbiosis cloud mentioned above refers to a cloud service platform built on cloud computing technology that supports the operation of the communication and navigation symbiosis system. The communication and navigation symbiosis cloud acts as a central hub for data storage, processing, analysis and exchange, providing support for various system components and promoting closer collaboration and symbiosis between them.

[0148] (2) Message transmission: The data exchange interface allows different types of messages and information to be transmitted between the satellite communication module and the satellite navigation module. These messages may include status reports, positioning data, communication quality information, etc.

[0149] Status Report: Satellite communication system can send status reports on communication link quality, signal strength, etc. to the symbiosis control module. Satellite navigation system can send status reports on positioning accuracy, satellite position, etc.

[0150] Positioning data: Satellite navigation systems can send positioning data to satellite communication systems so that the satellite communication systems can provide location information when precise positioning cannot be obtained.

[0151] Communication quality information: The satellite communication system can send communication link quality information to the satellite navigation system to help the satellite navigation system better estimate the user's location.

[0152] like Figure 4 The figure shows the symbiotic state and message transmission diagram.

[0153] Message 1: Reports on the status of the communication link quality, signal strength, etc. sent by the satellite communication system to the symbiosis control module.

[0154] Message 2: The symbiotic control module sends positioning data to the satellite communication system to provide it with precise positioning and enhance communication performance.

[0155] First of all, positioning data refers to the positioning data collected by the symbiotic control module. These data include the geographical coordinates (longitude, latitude, altitude), speed, direction and other information of the user device, and usually include the spatial location and motion status information of the user device.

[0156] When the satellite communication system obtains these positioning data, the following existing technical means can be used to enhance communication performance:

[0157] 1. Beamforming: Based on the precise positioning data of the user device, the satellite communication system can adjust the direction of the transmit or receive beam to transmit the communication signal to the target device more accurately and improve the signal quality.

[0158] 2. Spectrum Allocation: Based on user device positioning data, satellite communication systems can optimize spectrum allocation, avoid interference and improve communication reliability and speed.

[0159] 3. Adaptive Modulation and Coding: Dynamically adjust the modulation and coding of communication signals according to the user equipment positioning data and the quality of the communication link to adapt to the communication environment at different locations and improve communication efficiency.

[0160] 4. Multiple-antenna technology (MIMO): Using the positioning data of user equipment, satellite communication systems can implement multiple-input multiple-output technology, transmitting multiple data streams simultaneously through multiple antennas, improving communication capacity and reliability.

[0161] Message 3: The satellite navigation system sends status reports such as positioning accuracy and satellite position to the symbiosis control module. These reports usually include the following information:

[0162] 1. Position Accuracy: Indicates the accuracy of the device's location information, usually in units of distance (e.g. meters). The positioning accuracy report tells the receiver how far the device's current positioning result differs from its actual location.

[0163] 2. Satellite Positions: Indicates the position coordinates of each satellite in the satellite navigation system at the current time. This information includes the longitude, latitude, altitude, etc. of the satellite, which is used to calculate the location of the device. The satellite position information report tells the receiver the position of the satellites visible around the device in the sky.

[0164] Specific uses include:

[0165] Navigation and positioning: The receiver (symbiotic control module) can use the positioning accuracy information sent by the satellite navigation system to understand the current positioning accuracy of the user device, while the satellite position information helps the receiver calculate the exact location of the user device for navigation and positioning services.

[0166] Clock synchronization: The time of the satellite navigation system is usually synchronized with the atomic clock of the satellite system. The receiver can use the satellite position information to accurately synchronize the clock of the receiving device to ensure the time synchronization between the receiving device and the satellite system.

[0167] Environmental perception: Knowing the visible satellite positions around the receiving device can be used for environmental perception. For example, the positions of satellites around the device can be analyzed to determine whether there are any obstructions, thereby improving the signal reception quality.

[0168] Decision making: In some applications, such as meteorology and geological exploration, the accuracy of satellite position information is very important for decision making. The receiver can use this information to make relevant decisions.

[0169] It should be noted that the specific positioning accuracy and the format and accuracy of satellite position information may depend on the satellite navigation system used (such as GPS, GLONASS, Galileo, etc.) and the requirements of actual applications.

[0170] Message 4: The symbiosis control module sends the communication link quality information to the satellite navigation system to help the satellite navigation system better estimate the user's position.

[0171] Generally speaking, satellite communication link quality information usually includes the following:

[0172] 1. Signal Strength: Indicates the strength or weakness of a signal, usually measured in decibels (dB).

[0173] 2. Signal-to-Noise Ratio (SNR): Indicates the ratio between the signal and the background noise, usually in dB. The higher the signal-to-noise ratio, the better the signal quality.

[0174] 3. Signal Delay: It refers to the time required for a signal to travel from the sender to the receiver, usually in milliseconds. Low delay means small communication delay and fast signal transmission.

[0175] 4. Bit Error Rate (BER): Indicates the probability of bit errors occurring during signal transmission. A low bit error rate indicates stable signal transmission.

[0176] This information is usually detected by satellite communication equipment or ground station receiving equipment through corresponding sensors and measuring devices. For example, satellite receiving equipment may be equipped with an antenna to measure signal strength, and the circuit inside the receiver can calculate the signal-to-noise ratio. The delay is usually obtained by measuring the time difference between signal transmission and reception, and the bit error rate can be calculated by comparing the transmitted data with the received data.

[0177] Satellite navigation systems use this communication link quality information to estimate the user's position, usually in the following ways:

[0178] 1. Doppler Effect: When the satellite and the user move relative to each other, the frequency of the signal will change. By measuring the frequency change of the signal, the relative speed between the user and the satellite can be inferred for positioning.

[0179] 2. Signal Delay: It takes a certain amount of time for a signal to propagate. By measuring the time it takes for a signal to be sent from a satellite to a receiving device, the distance the signal has propagated can be calculated. Combining the signal delay information of multiple satellites, triangulation positioning can be used to determine the user's location.

[0180] 3. Signal strength and signal-to-noise ratio: A strong signal and a high signal-to-noise ratio generally indicate that the user is close to the satellite, while a weak signal and a low signal-to-noise ratio indicate that the user is far away. This information can be combined with the known position of the satellite and the signal propagation characteristics to estimate the user's location.

[0181] The specific positioning algorithms and methods may vary depending on the system design, but usually they will use satellite communication link quality information to improve the accuracy and reliability of positioning.

[0182] (3) Protocol description: In order to ensure the smooth data exchange, the data exchange interface needs to define a set of communication protocols to specify the message format, transmission method and processing method.

[0183] Message format: defines the structure and fields of the message, including the header, data part, and checksum, etc. This helps ensure the consistency and accuracy of the message. The purpose of designing the message format is to ensure the consistency and accuracy of the message. This means that whether there is a clear unified message format or not, if the information of the message is consistent between different communication and navigation modules, the communication quality and navigation accuracy will not be greatly affected.

[0184] A unified message format generally has the following benefits:

[0185] Consistency: A unified message format ensures that information exchanged between different systems has the same structure and fields, which helps avoid issues with misinterpretation or mismatches.

[0186] Accuracy: A unified message format can define the structure of the data, including fields such as checksums, to ensure the accuracy and integrity of the information.

[0187] While the lack of a unified message format may not immediately affect communication quality and navigation accuracy, it can lead to the following issues:

[0188] Interpretation and compatibility issues: If the message format between different systems is not clearly defined, it may lead to incorrect interpretation of the information or compatibility issues.

[0189] Difficult error handling: In the case of inconsistent message structure, incorrect message handling and troubleshooting may become more difficult.

[0190] Data integrity issues: The lack of a unified message format can make data integrity measures such as checksums difficult to implement, thereby reducing data integrity.

[0191] In summary, although there is no explicit mention of a unified message format, in order to ensure communication quality and navigation accuracy, it is very important to ensure that the information of the message is consistent between different modules and transmitted according to the defined structure. In actual systems, there are usually message protocols or standards to specify the format and fields of the message to ensure the reliability and performance of the system.

[0192] Transmission mode: Determine the transmission method of the message, including the frequency and rate of data transmission. This depends on the actual needs of the system and the performance of the communication medium.

[0193] Processing: describes how the message is processed, including the parsing, encoding, and decoding process of the message. This ensures that the message can be correctly converted between sending and receiving.

[0194] In the embodiments, the message format, processing method and transmission method in the protocol description may be innovatively optimized to meet specific requirements or improve system performance. Specific innovative optimizations may include the following aspects:

[0195] 1. Message format optimization: The message format in the protocol description may be optimized for actual application scenarios. For example, a compact binary format is used instead of a text format to reduce message transmission time and bandwidth consumption. Message format optimization may also include the use of extensible markup languages ​​(such as XML or JSON) for easy parsing and processing.

[0196] 2. Processing optimization: In terms of message processing, more efficient algorithms or data structures may be used to speed up message processing. For example, a fast hash algorithm is used to calculate the message checksum to ensure data integrity while reducing the computing load. In addition, the message processing process may also be optimized, using parallel processing or asynchronous processing to improve the system's response speed and throughput.

[0197] 3. Transmission mode optimization: In terms of message transmission, a more reliable and efficient transmission mode may be adopted. For example, forward error correction technology is introduced to automatically repair errors during transmission and improve data reliability. In addition, multi-path transmission or load balancing technology may be used to ensure that messages can be transmitted through multiple paths, improving the stability and fault tolerance of transmission.

[0198] 4. Security enhancement: Security innovations may be added to the protocol description, such as message encryption, digital signatures and other security mechanisms to ensure the confidentiality and authenticity of messages. These security enhancements can prevent malicious attacks and data tampering and improve the security of the system.

[0199] The data exchange interface in the satellite communication and navigation symbiosis framework is more than just a simple connection. It is the basis for information exchange between the satellite communication system and the satellite navigation system. Through appropriate hardware connections, message passing and protocol descriptions, the data exchange interface can achieve efficient, accurate and reliable data transmission, providing key support for the normal operation of the symbiotic system.

[0200] In the present invention, the key module algorithm flow includes the symbiotic control module algorithm flow and the data exchange interface algorithm flow, which are specifically:

[0202] Start: Start the Symbiosis Control Module.

[0203] Data collection: Monitor the status of satellite communication systems and satellite navigation systems, including signal strength, communication quality, satellite position, etc., and obtain real-time data through sensors and monitoring equipment.

[0204] Data analysis: Analyze the collected data to identify possible problems, bottlenecks or opportunities in the system. Evaluate communication quality and navigation accuracy. Evaluating communication quality and navigation accuracy usually involves the use of multiple techniques and algorithms. The following are some methods that may be used to evaluate communication quality and navigation accuracy:

[0205] Evaluate the quality of communication:

[0206] Signal strength and signal-to-noise ratio analysis: By analyzing the received signal strength and signal-to-noise ratio, the quality of the communication link can be assessed. Low signal-to-noise ratio and signal strength may indicate poor communication quality.

[0207] Bit error rate analysis: Evaluates the bit error rate that occurs during data transmission, usually using existing error detection and correction code technology, such as CRC (cyclic redundancy check) or Hamming code.

[0208] Delay analysis: By analyzing the propagation delay of the signal, the delay of the communication link can be evaluated. Higher delay may affect real-time requirements.

[0209] Evaluating navigation accuracy:

[0210] Utilization of the Doppler effect: By analyzing the changes in the received signal frequency, the relative speed between the user and the satellite can be calculated, thereby improving the accuracy of position estimation.

[0211] Triangulation: Using signal delay information from multiple satellites, combined with the known positions of the satellites, triangulation can be used to estimate the user's location.

[0212] Extended Kalman Filter (EKF): EKF is a filtering algorithm commonly used in navigation systems that can fuse multiple sensor data, including GPS signals, to improve the accuracy of position estimation.

[0213] Differential GPS: Use multiple GPS receivers, one of which serves as a base station. Other receivers correct their positions by comparing the signals from the base station to improve navigation accuracy.

[0214] Inertial navigation system: Uses sensors such as accelerometers and gyroscopes to measure motion status. Combined with time, it can calculate position information and provide high-precision navigation data.

[0215] Most of these algorithms and techniques are already available and are widely used in the field of satellite navigation and communications. The task of evaluating communication quality and navigation accuracy is usually done by system engineers, data analysts, or experts in related fields. They will select appropriate algorithms and techniques based on the needs of specific applications and use the collected data for analysis to evaluate the performance and accuracy of the system. If innovative algorithms or techniques are used in specific applications, their performance and feasibility are usually evaluated by researchers or development teams in related fields.

[0216] Intelligent decision-making: Make intelligent decisions based on the results of data analysis, such as adjusting the communication frequency band and transmission power.

[0223] 3. Adjust the communication frequency band and transmission power:

[0224] Frequency band adjustment: Use the spectrum analysis tool to select a frequency band with less interference in the current area. This can reduce signal interference and improve communication quality.

[0225] Transmit power adjustment: adjust the transmit power according to the communication distance and the sensitivity of the receiving device. Too high power may cause interference, while too low power may cause signal quality to deteriorate.

[0226] Implement adjustments: Implement adjustments in the system, update the settings of the satellite navigation system and the satellite communication system, and ensure that the new parameters take effect.

[0228] User demand response: Adjust strategies based on user needs and optimize system performance to meet special needs, such as special requirements in disaster relief scenarios.

[0229] End: The symbiosis control module enters a dormant state or continues to execute the above steps in a loop.

[0230] Figure 6 This is the data exchange interface algorithm flow chart, and the corresponding steps are as follows:

[0231] Start: Start the data exchange interface.

[0232] Message Generation: Satellite communication systems and satellite navigation systems generate different types of messages, such as status reports, positioning data, communication quality information, etc.

[0233] Message formatting: Format the generated message according to the predefined message format, including the header, data part and checksum.

[0234] Message transmission: The formatted message is transmitted to the corresponding module and / or system through a physical connection (wireless or wired), for example, the message of the satellite communication system is transmitted to the satellite navigation system.

[0235] Message reception: The receiving module and / or system receives the transmitted message and prepares for subsequent processing.

[0236] Message parsing: Parse the received message and extract the contents of the header and data to ensure the integrity and accuracy of the data.

[0237] Message processing: Perform corresponding processing based on the content of the message, for example, using positioning data for navigation calculations and using communication quality information for performance evaluation.

[0238] Feedback generation: Generate feedback messages based on processing results, which may include status confirmation, navigation instructions, etc.
