Description

Technical Field

[0001] The present invention belongs to the field of satellite communication technology, and specifically, relates to a method and system for in-orbit reconstruction and injection of a satellite with a ground measurement equipment communication function, and more particularly, relates to a general method and system for in-orbit efficient reconstruction and injection of a satellite with a ground measurement equipment communication function. Background Art

[0002] With the development of satellite development technology, communication, navigation, earth imaging and other types of satellites have made satellite system architecture flexible by carrying onboard products with software-defined functions, realizing on-orbit reconstruction of satellite functions and performance. In order to cope with the new trend of satellite development in the future, respond to the explosive growth of business needs of on-orbit satellites, and improve the autonomous operation capability of satellites, most satellites currently developed have on-orbit reconstruction functions to better solve the conflict problems of multi-task, strong dynamic and high-concurrency planning of large-scale star clusters, and adapt to the various business mission requirements of future satellites, star clusters and their constellations.

[0003] Satellite on-orbit reconstruction is generally updated by injecting on-orbit reconstruction data into the measurement and control high-speed injection channel. However, with the continuous expansion of on-orbit reconstruction needs and the continuous increase in the amount of reconstruction data, and due to the different requirements for setting the clear and secret states of satellite on-orbit reconstruction and the inconsistency of the satellite-to-ground communication interface, the existing on-orbit reconstruction data processing methods cannot be universal and are difficult to adapt to the diverse needs of different models and different on-board software, which puts forward higher requirements for the real-time, accuracy and efficiency of satellite on-orbit reconstruction data processing.

[0004] In response to the current satellite on-orbit reconstruction method, the patent document "A ground-based automatic verification system, device and method for on-orbit reconstruction of satellite-borne FPGA" (CN114816893A) solves the problem of complex on-orbit reconstruction operation and high error rate of satellite-borne FPGA. However, this method only solves the problem of automatic ground verification of on-orbit reconstruction of a single satellite-borne FPGA, and is not suitable for the whole satellite test scenario.

[0005] In addition, whether or not a satellite has the ability to communicate with ground test equipment has very different requirements for on-orbit reconstruction. The on-orbit reconstruction method for satellites with the ability to communicate with ground test equipment has special requirements in terms of data timeliness and data encryption. The existing on-orbit reconstruction methods all have the problem that the on-orbit reconstruction high-speed injection frames cannot be encrypted or injected in real time.

[0006] For example, the patent document "An Automatic Management System for On-orbit Reconfiguration of a Single Satellite Machine in Satellite-Ground Collaboration" (CN116467183A) discloses that the consistency of the satellite-ground reconstruction process is ensured through satellite-ground collaborative design, and a platform architecture is realized for on-orbit reconstruction verification of satellite stand-alone software. It can quickly perform verification and drills before on-orbit reconstruction of a single machine, solving the problem that there is currently no verification and drill platform that can be applied to on-orbit reconstruction of satellite stand-alone software. However, the system does not have the function of communicating with ground test equipment, and cannot verify the correctness of the on-orbit reconstruction data after processing by ground test equipment.

[0007] The patent document "Efficient Uploading Method and System for Intelligent Multi-Source Data" (CN117375692A) discloses a method and system that can intelligently identify the data type in the target multi-source data packet, complete the original data packet subpacketization processing and theoretical uploading time calculation, and solve the problem of low efficiency of existing uploading methods for reconstructing multi-source data. However, this method and system also do not have the function of communicating with ground test equipment and are not suitable for whole-satellite test scenarios.

[0008] The patent document "On-orbit Reconstruction Method and Device for Large-Scale FPGA Programs Suitable for Low-orbit Spacecraft" (CN117591467A) discloses a method and device for on-orbit reconstruction of large-scale FPGA programs by dividing the work between ground stations and satellites, using block transmission, multi-level verification and other means to greatly reduce the workload and solve the problem of efficient and reliable on-orbit reconstruction of large-scale FPGA programs. However, this method and device are only applicable to low-orbit spacecraft and cannot be used on all spacecraft, and do not have the ability to communicate with ground test equipment.

[0009] Therefore, a new satellite on-orbit reconstruction and annotation method is urgently needed to solve the current status of "diversified, complex formats, multiple requirements, and non-universal" in the processing of existing satellite on-orbit reconstruction data, solve the problem of universal processing of satellite on-orbit reconstruction data, and provide a stable and reliable verification and annotation system for the ground testing of the entire satellite and on-orbit reconstruction, so as to realize the universalization, efficiency and accuracy of on-orbit reconstruction data processing.

[0060] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0061] According to a satellite on-orbit reconstruction injection method with ground measurement equipment communication function provided by the present invention, Figure 1 For example, the following steps are included:

[0062] Step S1: Select the on-orbit reconstructed raw data file to be uploaded;

[0063] In more preferred examples, the on-orbit reconstructed original data file generally refers to the binary data file of the satellite stand-alone on-orbit reconstructible software; the satellite stand-alone on-orbit reconstructible software generally includes integrated electrical application software, operating system software, attitude and orbit control application software, FPGA processing software, data transmission CPU program, network terminal protocol processing software, etc.

[0064] Step S2: According to the satellite on-orbit reconstructed remote control frame format requirements, the original data file selected in step S1 is preprocessed to generate the satellite on-orbit reconstructed remote control frame, and the data reconstruction autonomous verification analysis is completed;

[0065] In more preferred examples, data preprocessing refers to data segmentation processing of the original data file reconstructed on-orbit according to the requirements of the size of each reconstructed data block in the satellite remote control implementation scheme.

[0066] The satellite remote control implementation plan is a design document for each satellite model (the document will generally not be changed after passing the review), including the satellite on-orbit reconstruction remote control frame format requirements, each reconstruction data block size requirements, clear and secret state setting requirements, scrambling processing requirements, framing form requirements, etc., which are all regular settings for one-time configuration. However, there are certain differences in the frame format between each satellite model. In order to achieve the universalization of the on-orbit reconstruction method and system, its frame format and data block requirements are split into multiple system configuration items for management, so that parameters can be configured and models can be universal.

[0067] The satellite on-orbit reconstructed remote control frame format requirements are generally specified by the satellite remote control implementation plan, which generally consists of a frame header and a frame data field. Figure 2 For example, the frame data field consists of a packet header and a packet data field.

[0068] The data reconstruction autonomous verification analysis refers to comparing and analyzing the data fields in the on-orbit reconstructed original data and the on-orbit reconstructed remote control frame to verify the consistency between the two.

[0069] Step S3: according to the setting requirements of the satellite on-orbit reconstruction of the clear and secret state, establish stable communication between the encryption and decryption machines, and complete the encrypted data replacement of the satellite on-orbit reconstruction remote control frame in step S2;

[0070] In more preferred examples, establishing stable communication with the encryption and decryption machine means using TCP / IP network communication protocol and SOCKET communication to establish two-way data communication with the encryption and decryption machine to achieve efficient and highly reliable data receiving and sending functions.

[0071] The requirements for setting the satellite’s on-orbit reconstruction state are generally specified by the satellite remote control implementation plan. For the secret state remote control frame, Figure 3 For example, its frame format generally consists of a frame header, a frame data field and an encryption key number.

[0072] Step S4: scrambling the satellite on-orbit reconstruction remote control frame encrypted in step S3;

[0073] The scrambling algorithm is generally specified by the satellite remote control implementation plan, which generally involves randomizing the satellite's in-orbit reconstructed remote control frames.

[0074] Step S5: Generate a satellite on-orbit reconstruction high-speed injection frame according to the requirements of the satellite on-orbit reconstruction framing format and the satellite on-orbit reconstruction remote control frame after scrambling in step S4, and complete the data injection autonomous verification analysis;

[0075] The requirements for the satellite on-orbit reconstruction framing format are generally specified by the satellite remote control implementation plan, and are generally composed of a transmission frame header, an insertion field, valid data, and a frame error control field. The valid data generally consists of a synchronization word, a frame data field (satellite on-orbit reconstruction remote control frame after scrambling), and a fill word. The satellite on-orbit reconstruction high-speed frame format is as follows Figure 4 shown.

[0076] The data upload autonomous verification analysis refers to comparing and analyzing the high-speed upload frame of the current on-orbit reconstruction with the high-speed upload frame of the last on-orbit reconstruction of the same data block to verify the consistency between the two.

[0077] Through two independent data verification analyses, the accuracy of the uploaded data is ensured, and the correctness of the high-speed uploaded frames generated by the verification process is verified to avoid the failure of the satellite's on-orbit reconstruction mission or even damage to the on-board products.

[0078] Step S6: According to different high-speed injection baseband device protocols, the protocol adaptation of the satellite on-orbit reconstructed high-speed injection frame and the ground high-speed injection baseband device in step S5 is completed, and the adapted data is sent to the ground high-speed injection baseband device through the network;

[0079] The high-speed uplink baseband device protocol is a universal protocol in the prior art. Since the high-speed uplink baseband device protocols of different manufacturers are different, it is necessary to adapt to the device protocol. The present invention is compatible with different high-speed uplink baseband protocols through parameter configuration and has universality. The input of the ground high-speed uplink baseband device is the satellite on-orbit reconstructed high-speed uplink frame in step S5.

[0080] Step S7: According to steps S1-S6, a satellite on-orbit reconstruction autonomous verification and efficient uploading system is established. The system has the functions of satellite on-orbit reconstruction data uploading, settable uploading rate, autonomous data verification and analysis, and dynamic monitoring of the uploading process.

[0081] According to the present invention, a satellite on-orbit reconstruction and injection system with a ground measurement equipment communication function is provided, which is a satellite on-orbit reconstruction and injection general system with high efficiency, which is formed according to the satellite on-orbit reconstruction and injection method with a ground measurement equipment communication function. Figure 5For example, it includes: configuration management module, data service module, communication interface module;

[0082] The configuration management module has the functions of remote control package parameter setting, remote control frame parameter setting, injection rate setting, verification selection, scrambling selection, etc.; the data service module has the functions of data file segmentation, batch generation of remote control packages, batch generation of remote control frames, data autonomous verification and analysis, etc.; the communication interface module has the functions of communication protocol adaptation, encrypted data interaction, data transmission control, etc.

[0083] The configuration management module takes universal design into consideration. By analyzing the on-orbit reconstructed remote control frame format and the on-orbit reconstructed high-speed injection frame format in the remote control implementation plan of each satellite model, the maximum envelope is summarized, and the remote control frame format and the high-speed injection frame format are decomposed into configurable configuration items, so as to meet the requirements of different satellite models and improve universality.

[0084] The communication interface module can communicate with the dedicated encryption and decryption equipment of each satellite model and complete the encryption and decryption data exchange. Since the secret keys of each satellite model cannot be publicly obtained and are only bound to their dedicated encryption and decryption equipment, the encryption and decryption equipment dedicated to each model must be connected to the system through the encrypted data exchange function in the communication interface module to establish a stable communication connection, ensure the encryption capability of the remote control frame data reconstructed on-orbit, and ensure the timeliness of data interaction to meet the timeliness of high-speed injection, achieve the ability of real-time injection, meet the requirements of satellite on-orbit reconstruction data, and specifically solve the problem that the high-speed injection frame cannot be encrypted and cannot be injected in real time during on-orbit reconstruction, avoiding mission failure.

[0085] The overall workflow of the satellite on-orbit reconfiguration and efficient injection general system is as follows: Figure 6 The interface of the satellite on-orbit efficient reconfiguration system is shown in Figure 7 shown.

[0086] There is a dynamic monitoring area for the upload process on the general system interface for efficient upload of satellite on-orbit reconstruction, which contains information such as the send frame count and receive frame count of the current on-orbit reconstruction task.

[0087] The data service module selects the raw data files of on-orbit reconstruction to be uploaded for pre-processing, generates satellite on-orbit reconstruction remote control frames, and completes autonomous verification and analysis of data reconstruction;

[0088] The communication interface module establishes stable communication with the encryption and decryption machine, completes the encrypted data replacement of the satellite's on-orbit reconstruction remote control frame, and obtains the secret remote control frame;

[0089] The configuration management module manages parameters and functional configuration items;

[0090] The data service module completes the scrambling process according to the scrambling process configuration items of the function configuration items in the configuration management module, generates the satellite on-orbit reconstruction high-speed injection frame according to the satellite on-orbit reconstruction framing form requirements and the scrambled secret remote control frame, and completes the data injection autonomous verification analysis;

[0091] The communication interface module completes the protocol adaptation of the satellite's in-orbit reconstruction of the high-speed injection frame, and sends the adapted data to the ground high-speed injection baseband equipment through the network.

[0092] The configuration management module, data service module and communication interface module cooperate with each other. Since the configuration management module has the characteristics of universal configuration of frame formats of various satellite models, the data service module can call the communication interface module to generate on-orbit reconstruction high-speed injection frames that meet the requirements of the satellite remote control implementation plan based on the configuration items of the configuration management module, thereby solving the problems of universalization and accuracy of satellite on-orbit reconstruction.

[0093] In more preferred embodiments, the on-orbit reconstructed raw data file includes a binary data file of integrated power application software, operating system software, attitude and orbit control application software, FPGA processing software, data transmission CPU program or network terminal protocol processing software;

[0094] The data service module performs data segmentation processing on the on-orbit reconstructed original data file according to the requirements of the reconstructed data block size in the satellite remote control implementation scheme;

[0095] The satellite on-orbit reconstructed remote control frame includes a frame leader header and a frame data field, and the frame data field includes a packet leader header and a packet data field;

[0096] The communication interface module sets the satellite on-orbit reconstructed remote control frame to a frame format consisting of a frame leading header, a frame data field and an encryption key number according to the set satellite remote control implementation scheme, thereby obtaining a secret remote control frame;

[0097] The stable communication of the encryption and decryption machine is to establish two-way data communication with the encryption and decryption machine by using TCP / IP network communication protocol and SOCKET communication.

[0098] In more preferred embodiments, the scrambling process includes a randomization process;

[0099] The satellite on-orbit reconstruction framing form is required to be a transmission frame leading header, an insertion field, valid data and a frame error control field to form a satellite on-orbit reconstruction high-speed injection frame format;

[0100] The effective data includes a synchronization word, a frame data field and a filling word, and the encrypted remote control frame after scrambling is in the frame data field.

[0101] In more preferred examples, the data reconstruction autonomous verification analysis is to compare the frame data field of the on-orbit reconstructed original data file with the on-orbit reconstructed remote control frame to verify the consistency;

[0102] The data injection autonomous verification analysis is to compare the current on-track reconstruction high-speed injection frame of the same data block with the previous on-track reconstruction high-speed injection frame to verify consistency;

[0103] The communication interface module completes the protocol adaptation of the satellite's on-orbit reconstructed high-speed injection frame and the ground high-speed injection baseband device according to different high-speed injection baseband device protocols, and sends the adapted data to the ground high-speed injection baseband device through the network.

[0104] Through autonomous and intelligent scheduling of data subpackaging, scrambling, encryption, distribution and verification, the universalization, efficiency and accuracy of on-orbit reconstruction data processing are achieved, which greatly improves the efficiency of satellite on-orbit reconstruction and provides technical support for rapid response to the strong dynamic, high concurrency and ultra-fine on-orbit reconstruction needs of future satellites, star clusters and constellations.
