Problems solved by technology

[0002] In the hardware design of traditional satellites, fault handling is usually achieved by using a stand-alone or board master switch backup method, and software abnormalities are usually simply handled by switching off or resetting, but with the continuous improvement of satellite intelligence and software functions The original design method cannot guarantee that the satellite has strong fault repair and software upgrade capabilities in orbit, and the reconfigurable and modifiable architecture design of the on-board software has become the mainstream technology route for the current and future development of small satellites
Compared with the switch-off and reset operations, the on-orbit reconstruction process is more complicated and needs to be very precise, otherwise not only the fault repair cannot be performed, but also the software may be confused, causing more severe faults on the satellite

Embodiment

[0053] In the following, a specific example is used to illustrate the steps of the method for on-board software annotation and reconstruction of the small satellite according to the present invention.

[0054] Step S1, generating a test case file to be marked or reconstructed for the GNSS receiving subsystem. Here the GNSS receiving subsystem is the lower computer to be reconfigured.

[0055] In this embodiment, on the basis of the navigation information processing software of the GNSS receiving subsystem, the leading header including the version number, spacecraft identification word, virtual channel identification word, frame length, and frame sequence number is automatically added, and errors are automatically added. Controlled XOR and checkword form a test case file.

[0056] Step S2, sending the test cases to be placed or reconstructed to the satellite through the measurement and control baseband high-speed uplink channel.

[0057] In this embodiment, the uplink channel...

Abstract

The invention discloses a minisatellite on-satellite software injection and reconstitution ground test validation method, comprising the following steps: (1) using an automation method to generate a test case to be injected and reconstituted; (2) sending the test case to be injected and reconstituted to a tested minisatellite through a measurement and control baseband uplink channel; (3) performing comparison and analysis on the test case to be injected and reconstituted, received by a platform integrated electronic device, with the test case to be injected and reconstituted, sent by a groundmeasurement and control baseband device, to verify a measurement and control baseband uplink channel communication link and a communication link between a measurement and control all-in-one machine and the platform integrated electronic device; (4) judging the integrity and correctness of acceptance of the test case to be injected or reconstituted through telemetry data of a lower computer to be injected or reconstituted; (5) verifying the correctness of the version identification of the lower computer to be injected or reconstituted so as to verify a modification configuration parameter and areconstitution function of the lower computer; and (6) performing a detailed test of function and performance on the lower computer so as to check the function and performance of a new program of thelower computer.
