Description

Technical Field

[0001] This invention relates to the field of space-to-ground and inter-satellite laser communication technology, and in particular to a method for inter-satellite laser interconnection links. Background Technology

[0002] Interplanetary laser-based satellite interconnection is a technology that uses laser beams to establish communication links between Earth and satellites, also known as laser-interplanetary links. In this technology, a ground station uses a high-energy laser to modulate data onto a laser beam, which is then transmitted to the target satellite. The receiver on the target satellite receives the laser beam, demodulates, detects, and amplifies it to recover the original data. This method enables stable communication between Earth and satellites.

[0003] However, the longer the transmission distance of laser communication, the more severe the signal attenuation and scattering during transmission, leading to increased transmission delay. Summary of the Invention

[0004] The purpose of this invention is to provide a method for interstellar laser interconnection links, which solves the problem that the longer the transmission distance of laser communication, the more severe the signal attenuation and scattering during the transmission process, leading to increased transmission delay.

[0005] To achieve the above objectives, the present invention provides a method for interstellar laser interconnection of 10,000 stars, comprising the following steps: Determine the satellite orbits and number; Based on the principle of a three-column magic square, the selected satellites are distributed on three different orbital planes to form a Rubik's Cube-shaped structure; High-precision telescopes and laser communication equipment are installed on each satellite; Using laser communication technology, a stable communication link can be established between adjacent satellites; Establish communication protocols and data transmission control mechanisms; After establishing the link, conduct testing and debugging; During operation, the link is regularly maintained and monitored.

[0006] The steps of determining the satellite orbit and number also include: Create an Earth model; Based on requirements and Earth models, determine appropriate orbital parameters; Calculate the required number of satellites based on demand and orbital parameters.

[0007] Based on the principle of a three-column magic square, selected satellites are distributed on three different orbital planes to form a Rubik's Cube-shaped structure. The steps also include: Determine the inclination angle of each track surface; Determine the height of each track surface; On each orbital plane, the satellite's position is determined according to the principle of a three-column magic square; Adjust the phase relationship between satellites.

[0008] In each orbital plane, the satellite's position is determined based on the principle of a three-column magic square. The steps also include: The satellites are arranged according to the row, column, or diagonal pattern of a magic square to ensure that they form a geometric pattern resembling a Rubik's Cube in space.

[0009] The step of establishing a stable communication link between adjacent satellites using laser communication technology also includes: Terminal B continues to emit beacon light until the satellite terminal detects the beacon light; After terminal A captures the beacon light emitted from terminal B, it simultaneously emits a narrow beam of beacon light to terminal B. After receiving the beacon light from each other, the two communicating parties switch from the coarse tracking stage to the fine tracking stage to perform high-precision tracking and keep the optical axes of both parties aligned. After the two communicating parties have been tracking each other stably for a period of time, they can transmit communication signal light with a small beam divergence angle to establish a stable communication link until the information transmission is completed.

[0010] The steps of establishing communication protocols and data transmission control mechanisms further include: Determine the communication protocol; Design a data transmission control mechanism; The specific data transmission process is determined based on the communication protocol and data transmission control mechanism; Based on the established communication protocol, data transmission control mechanism, and data transmission process, develop laser communication software between satellites; Through simulation testing and real-world scenario testing, the correctness and reliability of the communication protocol, data transmission control mechanism, and data transmission process are verified. Based on the test and verification results, necessary optimizations and improvements were made to the communication protocol, data transmission control mechanism, and data transmission process. The developed communication software is deployed to the satellite.

[0011] This invention discloses a method for interconnecting 10,000 satellites using interstellar laser technology. Based on service requirements and network topology, the number of satellites to be interconnected and their orbital parameters are determined. Appropriate orbital altitudes, inclinations, and perigee arguments are selected to ensure the satellites are distributed around the Earth according to a three-axis magic square pattern. Based on the principle of the magic square, the selected satellites are distributed across three different orbital planes, forming a structure similar to a Rubik's Cube. The number of satellites on each orbital plane can be adjusted as needed, but a certain regularity and symmetry must be maintained. A high-precision telescope and laser communication equipment, including a laser transmitter and receiver, are installed on each satellite. The pointing accuracy of the telescope and laser is ensured by calibrating the telescope and laser. These devices can accurately align with adjacent satellites for communication, establishing stable communication links between them using laser communication technology. By modulating and demodulating laser signals, they achieve data transmission and communication functions. Based on service requirements and network topology, they establish communication protocols and data transmission control mechanisms, including protocols and control mechanisms for data format, transmission rate, bit error rate, and flow control. After establishing the link, testing and debugging are performed to ensure its stability and reliability, including signal quality testing, transmission distance testing, and anti-interference capability testing. During operation, the link is regularly maintained and monitored to ensure its normal operation, including equipment status checks, troubleshooting, and system upgrades. The three-column magic square structure keeps the relative positions of the satellites stable, which is conducive to establishing stable and reliable communication links. By optimizing orbital parameters and satellite layout, long-term stable communication connections can be achieved. Due to the use of laser communication technology, data transmission rates are high, enabling rapid transmission of large amounts of data, which helps meet various business needs, such as high-definition video transmission and big data processing. Laser communication has a short transmission wavelength, making it less susceptible to radio wave interference. Furthermore, the use of a three-column magic square structure provides redundancy in the communication links between satellites, improving anti-interference capabilities. The short wavelength of laser communication makes it difficult to detect and intercept, and the three-column magic square structure enhances the confidentiality and security of the communication links. Compared to traditional radio wave communication, laser communication requires less spectrum resources, saving valuable spectrum resources. The method of establishing inter-satellite laser interconnection links using a three-column magic square structure can be expanded according to business needs, increasing or decreasing the number of satellites and adjusting orbital parameters to meet constantly changing requirements. Laser communication has low transmission latency, providing low-latency communication services, which is of great significance for applications with high real-time requirements, such as remote control and real-time monitoring.

Figure 2 This is a flowchart illustrating the steps of determining the satellite orbit and number according to the present invention.

Figure 5 This is a flowchart illustrating the steps of establishing the communication protocol and data transmission control mechanism of the present invention. The present invention provides a method for interstellar laser interconnection links, comprising the following steps: S100: Determine the satellite orbit and number; S101: Establishing an Earth model; S102: Determine appropriate orbital parameters based on requirements and Earth model; S103: Calculate the required number of satellites based on requirements and orbital parameters.

[0021] Specifically, the first step is to clarify the business requirements, such as the area to be covered, data transmission rate, and communication reliability. These requirements will directly affect the selection of satellite orbits and the number of satellites. An Earth model is then established, taking into account the Earth's shape, size, rotation, and magnetic field characteristics. This helps determine suitable orbital parameters and satellite positions. Based on the business requirements and the Earth model, appropriate orbital parameters are determined, such as altitude, inclination, perigee argument, and eccentricity. These parameters affect the satellite's coverage and transmission performance. Based on the business requirements and orbital parameters, the required number of satellites is calculated, taking into account factors such as the coverage area requirements, communication link reliability requirements, and satellite redundancy.

[0022] S200: Based on the principle of a three-column magic square, selected satellites are distributed on three different orbital planes to form a Rubik's Cube-shaped structure; S201: Determine the inclination angle of each track surface; S202: Determine the height of each track surface; S203: On each orbital plane, the satellite's position is determined according to the principle of a three-column magic square; S204: Adjust the phase relationship between satellites.

[0023] Specifically, based on business requirements and the number of satellites, the number of orbital planes to be formed is determined. In this example, three different orbital planes are formed. Based on the Earth model and business requirements, the inclination angle of each orbital plane is determined. The inclination angle is the angle between the orbital plane and the Earth's equatorial plane; different inclination angles affect the satellite's coverage and transmission performance. Based on business requirements and the Earth model, the altitude of each orbital plane is determined. The orbital plane altitude is the distance of the satellite from the Earth's surface; the higher the altitude, the wider the coverage, but the transmission delay will increase. On each orbital plane, the satellite's position is determined according to the principle of a three-column magic square, specifically arranged according to the row, column, or diagonal pattern of the magic square. Satellites are designed to form a regular geometric pattern in space, including a Rubik's Cube shape. The phase relationships between satellites are adjusted according to business requirements and communication protocols. Phase relationship refers to the offset between the relative positions of satellites. By adjusting the phase, the performance of the communication link can be optimized. Simulation and testing tools are used to verify the stability and reliability of the formed Rubik's Cube-shaped structure. The tests include, but are not limited to, the performance of the communication link, coverage, and transmission delay. Based on the verification and testing results, satellites or orbital planes that do not meet the requirements are adjusted and optimized. Then, satellite manufacturing, launch, and on-orbit deployment are carried out to ensure the satellites operate normally and meet business requirements.

[0024] S300: Each satellite is equipped with a high-precision telescope and laser communication equipment; Specifically, first, suitable high-precision telescopes and laser communication equipment are selected. These devices should possess characteristics such as high sensitivity, low noise, and high stability to meet the communication requirements in the space environment. To ensure the stability and reliability of the equipment, a specialized installation structure is designed, including shockproof devices, temperature control devices, and waterproof devices, to ensure the equipment operates normally in the space environment. The selected telescopes and laser communication equipment are then installed on the satellite according to the design requirements and secured. During installation, the pointing accuracy and stability of the equipment must be ensured to meet communication requirements. Finally, the telescopes and laser communication equipment are connected to the satellite's control system and preliminary debugging is performed, including adjusting the power supply to the equipment. The equipment undergoes debugging in areas such as electrical components, data transmission, and control signals to ensure normal operation. During the calibration and testing phase, a comprehensive evaluation of the equipment's performance is conducted, including calibration of the optical system, testing of laser communication, and assessment of the overall system performance, to ensure that the equipment's performance meets requirements in practical applications. Actual communication tests are performed to verify the equipment's data transmission capabilities and communication effectiveness, which is accomplished through communication experiments with ground stations or other satellites to verify the equipment's reliability and stability. During satellite operation, the equipment is regularly maintained and inspected to ensure its normal operation. For equipment requiring upgrades, corresponding upgrades are carried out to maintain the equipment's performance and technological advancement.

[0025] S400: Utilizes laser communication technology to establish stable communication links between adjacent satellites; S401: Terminal B continues to emit beacon light until the satellite terminal detects the beacon light; S402: After terminal A captures the beacon light emitted from terminal B, it simultaneously emits a narrow beam of beacon light to terminal B. S403: After receiving the beacon light from each other, the two communicating parties switch from the coarse tracking stage to the fine tracking stage to perform high-precision tracking and keep the optical axes of both parties in sync. S404: After the two communicating parties have been tracking each other stably for a period of time, they can emit a communication signal light with a very small beam divergence angle to transmit information and establish a stable communication link until the information transmission is completed.

[0026] Specifically, terminal B continuously emits beacon light until the satellite terminal detects the beacon light. After terminal A captures the beacon light emitted from terminal B, it simultaneously emits a narrow beam of beacon light to terminal B. At this point, both communicating parties can detect each other's beacon light. After receiving the beacon light from each other, both parties switch from the coarse tracking stage to the fine tracking stage to perform high-precision tracking, ensuring that the optical axes of both parties remain aligned. After both parties have been tracking each other stably for a period of time, they can emit communication signal light with a very small beam divergence angle to transmit information and establish a stable communication link until the information transmission is complete.

[0027] S500: Establishes communication protocols and data transmission control mechanisms; S501: Determine the communication protocol; S502: Design a data transmission control mechanism; S503: Determine the specific process of data transmission based on the communication protocol and data transmission control mechanism; S504: Based on the established communication protocol, data transmission control mechanism, and data transmission process, develop laser communication software between satellites; S505: Verify the correctness and reliability of the communication protocol, data transmission control mechanism, and data transmission process through simulation testing and real-world scenario testing; S506: Based on the test and verification results, make necessary optimizations and improvements to the communication protocol, data transmission control mechanism, and data transmission process; S507: Deploy the written communication software onto the satellite.

[0028] Specifically, based on business needs and technical requirements, a suitable communication protocol is determined. This protocol should include specifications for data format, transmission rate, bit error rate, flow control, etc. Existing communication protocols can be selected, or customized protocols can be developed as needed. To ensure the reliability and real-time performance of data transmission, appropriate data transmission control mechanisms need to be designed, including control mechanisms at the data link layer, network layer, and application layer, such as flow control, congestion control, and error control. Based on the communication protocol and data transmission control mechanisms, the specific data transmission process is determined, including steps such as data packaging, sending, receiving, and unpacking, as well as mechanisms for exception handling and error correction. Based on the determined communication protocol, data transmission control mechanisms, and data transmission process, laser communication software suitable for inter-satellite communication is developed. The software should possess functions such as data transmission, reception, parsing, and processing, and be able to effectively interact with ground stations. Through simulation and real-world scenario testing, the correctness and reliability of the communication protocol, data transmission control mechanism, and data transmission process should be verified. Testing should cover various scenarios and abnormal situations to ensure stability and reliability in practical applications. Based on the test and verification results, necessary optimizations and improvements should be made to the communication protocol, data transmission control mechanism, and data transmission process, including parameter adjustments, algorithm improvements, and performance enhancements, to meet the needs and technical requirements of practical applications. The developed communication software should be deployed to the satellite and tested in real-world scenarios. During deployment, attention should be paid to security and reliability to ensure the software operates normally and meets business requirements.

[0029] S600: After establishing the link, conduct testing and debugging; Specifically, first, test the basic functions of the link to ensure they are normal, such as sending and receiving data packets, confirming the integrity and correctness of the data packets, and evaluating the link's performance, such as transmission rate, latency, and packet loss rate. These parameters should meet the expected business needs and technical requirements. Test the link's performance under abnormal conditions, such as power outages, interference, and noise, to ensure the link remains stable under these conditions. Verify the link's compatibility with other devices or systems, such as whether communication with ground stations or other satellites is normal. Assess the link's security, such as whether encryption and authentication functions are normal, to ensure data security during transmission. Based on the test results, perform necessary debugging and optimization of the link, including adjusting parameters, improving algorithms, or fixing errors. Record the testing and debugging process and results in detail and write a report to help with subsequent maintenance and upgrade work.

[0030] S700: During operation, the link is regularly maintained and monitored.

[0031] Specifically, based on the characteristics of the link and business requirements, a plan for regular maintenance and monitoring should be developed, including the frequency, content, methods, and responsible personnel for maintenance. The link status should be monitored regularly through satellite monitoring systems or ground stations, including parameters such as transmission quality, latency, and packet loss rate, as well as the temperature, voltage, and current of the equipment. Once a link fault or performance degradation is detected, fault diagnosis and location should be immediately performed to analyze the cause of the fault, determine its location, and develop corresponding repair measures. Preventative maintenance should be carried out based on the link's operational status and historical data, such as regularly cleaning the optical system and replacing aging components, to prevent faults from occurring. To improve link reliability, backup and redundancy mechanisms should be established, for example, by setting backup devices or paths at critical nodes of the link to enable rapid switching in case of primary link failure. The maintenance and monitoring process and results should be recorded in detail, and reports should be written to help understand the link's operational status and provide a basis for subsequent maintenance and upgrades. With technological advancements and changes in business requirements, the link should be regularly upgraded and updated, including equipment replacement, software upgrades, and communication protocol updates.

[0032] The triple magic square structure ensures stable relative positions between satellites, facilitating the establishment of stable and reliable communication links. By optimizing orbital parameters and satellite layout, long-term stable communication connections can be achieved. Due to the use of laser communication technology, data transmission rates are high, enabling rapid transmission of large amounts of data, which helps meet various business needs, such as high-definition video transmission and big data processing. Laser communication has a short transmission wavelength, making it less susceptible to radio wave interference. Furthermore, the triple magic square structure provides redundancy in the communication links between satellites, improving anti-interference capabilities. The short wavelength of laser communication makes it difficult to detect and intercept, and the triple magic square structure enhances the confidentiality and security of the communication links. Compared to traditional radio wave communication, laser communication requires less spectrum resources, saving valuable spectrum resources. The method of establishing inter-satellite laser interconnection links using triple magic squares can be expanded according to business needs, increasing or decreasing the number of satellites and adjusting orbital parameters to meet constantly changing requirements. Laser communication has low transmission latency, providing low-latency communication services, which is of great significance for applications with high real-time requirements, such as remote control and real-time monitoring.
