Abstract
Description
Technical Field
[0001] This invention relates to the field of satellite laser communication technology, and in particular to an automated link establishment method and system for laser communication terminals based on satellite service management. Background Technology
[0002] Inter-satellite laser communication terminals are typically installed between two satellites, enabling high-speed optical communication between them via space-based light transmission. Laser communication uses lasers as the light source, transmitting data through small wavelets to achieve high-speed, long-distance information transmission. Laser communication features large transmission bandwidth, strong anti-interference capabilities, strong anti-interception capabilities, and high security. It is widely used in high-speed information transmission scenarios such as inter-constellation and inter-satellite-to-ground communication.
[0003] Inter-satellite and satellite-to-ground laser communication technologies have formed relatively mature technical systems and routes, and have completed on-orbit verification of interconnection and interoperability among multiple platforms and manufacturers. Laser communication technology can be applied to high-speed communication scenarios such as inter-satellite, satellite-to-ground, space-to-space, air-to-space, air-to-ground, and ground-to-ground communication. Currently, laser communication technology is being widely used in the construction of large constellation networks, such as Starlink and national internet constellations. Stable communication technology of laser communication terminals is the foundation for information transmission in inter-satellite networks.
[0004] With the development of laser communication technology, it has evolved through two-way laser communication achieved by guiding signal light with beacon light and direct signal light communication without beacon light guidance. The beacon light approach achieves wide divergence angle guidance during the initial link establishment phase, enabling rapid signal light acquisition. The beaconless approach uses signal light scanning coverage to achieve dual-terminal communication acquisition, offering advantages such as miniaturization and low cost.
[0005] For current laser communication solutions without beacon beams, the inter-satellite laser link establishment process is relatively complex. Both laser communication terminals need to agree on the roles of the scanning and staring ends according to the visible arc, the start and end times of scanning, and form a link establishment command sequence according to the agreement. The link establishment commands are generated in advance according to the corresponding times. The laser communication terminal involves functions such as optical head tracking and aiming control, optical amplifier optical power control, and communication modulation and demodulation. The number of commands involved is large and varies depending on the link establishment time and scenario. Summary of the Invention

[0018] Furthermore, the automated link establishment method for laser communication terminals based on satellite service management also includes a link establishment failure fallback mechanism:
[0019] If link establishment fails, the satellite service reconfigures the template command via ground control.

[0023] The command sending module is configured to, upon reaching the link establishment start time, invoke the link establishment template matching the target satellite identifier and send a command sequence to the laser communication terminal according to the time offset sequence; and
[0024] The link establishment completion module is configured to execute the instruction sequence of the laser communication terminal to complete the link establishment operation according to the link establishment end time.

[0042] In the following description, the invention is described with reference to various embodiments. However, those skilled in the art will recognize that the embodiments may be practiced without one or more specific details or with other alternatives and / or additional methods or components. In other instances, well-known structures or operations are not shown or described in detail so as not to obscure the inventive points of the invention. Similarly, for illustrative purposes, specific numbers and configurations are set forth to provide a comprehensive understanding of embodiments of the invention. However, the invention is not limited to these specific details.
[0043] In this specification, references to "an embodiment" or "this embodiment" mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in at least one embodiment of the invention. The phrase "in one embodiment" appearing throughout this specification does not necessarily refer to the same embodiment in all instances.
[0044] It should be noted that the embodiments of the present invention describe the method steps in a specific order; however, this is only for illustrating the specific embodiment and not for limiting the order of the steps. On the contrary, in different embodiments of the present invention, the order of the steps can be adjusted according to actual needs.
[0045] In this invention, the modules of the system according to the invention can be implemented using software, hardware, firmware, or a combination thereof. When a module is implemented using software, its function can be implemented through computer program flow. For example, the module can be implemented using code segments (such as code segments in languages like C and C++) stored in a storage device (such as a hard disk, memory, etc.), wherein the corresponding function of the module can be implemented when the code segment is executed by a processor. When a module is implemented using hardware, its function can be implemented by setting a corresponding hardware structure. For example, the module's function can be implemented by hardware programming a programmable device such as a field-programmable gate array (FPGA), or by designing an application-specific integrated circuit (ASIC) that includes multiple transistors, resistors, capacitors, and other electronic devices. When a module is implemented using firmware, the module's function can be written into a read-only memory such as an EPROM or EEPROM in the form of program code, and the corresponding function of the module can be implemented when the program code is executed by a processor. In addition, some functions of the module may need to be implemented by separate hardware or by working in cooperation with the hardware. For example, the detection function is implemented by a corresponding sensor (such as a proximity sensor, accelerometer, gyroscope, etc.), the signal transmission function is implemented by a corresponding communication device (such as a Bluetooth device, infrared communication device, baseband communication device, Wi-Fi communication device, etc.), the output function is implemented by a corresponding output device (such as a display, speaker, etc.), and so on.
[0046] This invention addresses the complexity of link establishment and reconnection after link loss for inter-satellite laser communication terminals in large constellations. Through overall satellite design, it improves the ease of inter-satellite link establishment and enhances system availability. The automated link establishment method for laser communication terminals based on satellite management provided by this invention solves the problem of automated onboard link establishment processes under different link establishment requirements at different times on the same satellite. Satellite management enables link establishment task management and automated template scheduling for all terminals. It is applicable to the adaptive time reference, local satellite attitude, local satellite orbit, and other satellite orbit broadcasts for multiple different terminals at different link establishment times, adaptively matching input information for link establishment at different times and with different target satellites.
[0047] Figure 1 A flowchart illustrating an embodiment of the automated link establishment method for laser communication terminals based on satellite management is shown below. Figure 1 This invention describes the automated link establishment method for laser communication terminals based on satellite management proposed in this invention. In one embodiment of this invention, the automated link establishment method for laser communication terminals based on satellite management can be executed by a computer. Figure 1 As shown, the automated link establishment method for laser communication terminals based on satellite service management includes the following steps:
[0048] First, the link establishment schedule uploaded by the ground telemetry and control system is received and stored, wherein the link establishment schedule includes the target satellite identifier, the laser communication terminal identifier, the link establishment start time, and the link establishment end time.
[0049] The ground-based telemetry and control system provides the basic information required for link establishment, such as the orbital information of the local satellite and the target satellite. The main elements of the link establishment schedule include the constellation target satellite identifier (ID), the laser communication terminal identifier (ID), and the start and end times of link establishment for each laser communication terminal. In one embodiment of the invention, for link establishment tasks involving multiple satellites within a constellation, the link establishment schedule may include information such as the satellites involved in the link establishment, the start time period, and the end time period. Onboard satellite staff stores and recalls automated link establishment procedures, selecting different link establishment templates according to different link establishment scenarios to achieve automated link establishment. In one embodiment of the invention, if it only involves satellite staff calling the procedure according to the instruction sequence, the satellite staff can simultaneously manage dozens of individual satellite terminals; typically, four terminals are configured on the satellite.
[0050] Next, a preset connection establishment template is matched according to the connection establishment scenario. This template includes a laser communication terminal identifier, a template identifier, an instruction sequence, and a time offset sequence. The satellite system allocates and configures templates according to the connection establishment scenarios of different terminals, and uploads the connection establishment templates. In one embodiment of the invention, connection establishment scenarios include multiple types, and different connection establishment scenarios are bound to different connection establishment templates. In one embodiment of the invention, the connection establishment template supports both beacon light and beacon-less schemes. In one embodiment of the invention, the beacon light scheme connection establishment template may include a beacon light activation instruction and scanning parameters; the beacon-less scheme connection establishment template may include a signal light power control instruction and scanning parameters.
[0051] In one embodiment of the present invention, a link establishment template management function based on the satellite service instruction sequence can be designed. The set link establishment template may include multiple link establishment templates. The number of instructions supported by the terminal and the instruction length of each link establishment template are designed and determined according to the number of instructions for the terminal link establishment. Different terminal identifiers, number of instruction templates, template IDs, time offsets and instruction frames in the templates are designed for different links allocated on the satellite. Figure 2 A schematic diagram of a link-building template format according to an embodiment of the present invention is shown. Figure 2 As shown, each link establishment template includes a laser communication terminal identifier (i.e., the terminal identifier in the figure), a template identifier (i.e., the template ID in the figure), an instruction sequence (instruction 1, instruction 2, ..., instruction n), a time offset sequence (time offset 1, time offset 2, ..., time offset n), and the number of template instructions, i.e., the value of n. Figure 2 As shown, the template content means: for a certain terminal, template number n contains a total of a instructions (a is the number of instructions in the template). When execution starts, for example, instruction 1 is executed at second 0, instruction 1 is executed after b seconds (b is the time offset 1), instruction 2 is executed after c seconds (c is the time offset 2), and so on, until the execution of the instructions is completed.
[0052] It should be noted that, Figure 2 The instructions in the command are pre-configured instructions for the terminal. After all instructions are executed, the connection establishment time will begin. These instructions are usually prepared in advance, and the response time is less than 1 second.
[0053] Different chain-building templates are designed according to different terminal parameter configurations for different chain-building scenarios under different constellations. The chain-building templates are allocated according to the chain-building templates, which can support chain-building sequences for different scenarios. Figure 3 This diagram illustrates the allocation of link establishment templates for different links according to an embodiment of the present invention. Figure 3 As shown, taking four links and 20 link establishment templates as an example, different template configurations can be selected during a single link establishment. In one embodiment of the invention, a single laser communication terminal establishes a link with only one target satellite at a time, avoiding command conflicts; multi-terminal tasks are scheduled according to the link establishment start time. Satellite time synchronization accuracy is achieved through on-board BeiDou / GPS timing, ensuring consistency across all satellites; therefore, the time offset definition in the link establishment template does not depend on satellite time synchronization accuracy.
[0054] Figure 4 This illustration shows a link establishment template and a link establishment scenario matching diagram for different links according to an embodiment of the present invention. Figure 4 As shown, different link-building templates can be bound to different link-building scenarios of the laser communication terminal. Automated template invocation is achieved through task identifiers in the link-building schedule or through command configuration. The number of link-building scenarios and templates can be expanded as needed. All ground command templates are stored on the satellite, and the ground configures template numbers according to different mission areas. Link-building template matching is configured on the satellite via commands. When the satellite is executed, it reads the configured link-building template identifier (i.e., the number). If link-building template 1 is configured, the satellite will automatically invoke link-building template 1. Different link-building templates correspond to different target satellites, and the terminal parameters may differ. These can be stored as different link-building templates, eliminating the need for frequent changes.
[0055] Next, the orbital data of the corresponding target star is extrapolated in real time based on the target star identifier, and the orbital data is broadcast to the laser communication terminal via point-to-point communication or broadcast communication. In one embodiment of the invention, 422 bus point-to-point communication or CAN bus broadcast communication can be used to broadcast the orbital data to the laser communication terminal. In another embodiment of the invention, the satellite administrator reads the target star ID information, start time, and end time of each link in the link establishment schedule, and extrapolates the target star orbit in real time according to the target star ID, realizing the broadcasting of orbits for different links according to the target star ID. When registering the orbit, it will include which star is being registered, and the satellite administrator will retrieve the corresponding star's orbit based on the target star of the link establishment and broadcast it.
[0056] Next, when the link establishment start time is reached, the link establishment template matching the target satellite identifier is invoked, and a sequence of instructions is sent to the laser communication terminal according to the time offset sequence.
[0057] Finally, based on the link establishment end time, the laser communication terminal executes the instruction sequence to complete the link establishment operation. In one embodiment of the invention, after the link establishment task is completed, the template instruction is invoked according to the end time. In another embodiment of the invention, the automated link establishment method for laser communication terminals based on satellite management also includes a link establishment failure fallback mechanism: if link establishment fails, satellite staff reconfigures the template instruction via ground control. It is worth noting that orbital broadcasting uses 422 point-to-point real-time broadcast communication or CAN bus broadcast communication, which has high reliability, and no cases of broadcast failure have been found on in-orbit satellites.
[0058] The proposed automated link establishment method for laser communication terminals based on satellite management can automatically schedule link establishment according to different working modes, supports link establishment start and end operations, and realizes link establishment task management and automated template scheduling for all terminals through satellite management, thereby improving the convenience of link establishment between laser communication terminals in constellations. It is applicable to the adaptive time reference, local satellite attitude, local satellite orbit, and other satellite orbit broadcasts of multiple different terminals at different link establishment periods, and adaptively matches the input information for link establishment of different time periods and different target satellites. The length, quantity, and scenario binding of instruction templates can all be flexibly configured, improving the robustness of laser communication terminal link establishment.
[0059] In one embodiment of the present invention, the present invention also provides a system for implementing the aforementioned automated link establishment method for laser communication terminals based on satellite management, such as... Figure 5 As shown, the system includes:
