Minisatellite on-satellite software injection and reconstitution ground test validation method and system

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.

Description

technical field [0001] The invention belongs to the technical field of satellite intelligence, and in particular relates to a small satellite on-board software annotation and reconstruction ground test verification method. Background technique [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 complica...
