Satellite-borne software in-orbit reconstruction association telemetering construction method and system, medium and equipment

Abstract

The invention provides a satellite-borne software in-orbit reconstruction association telemetering construction method and system. The method comprises the steps that satellite-borne software verifies a reconstruction package and verifies the reconstruction package; and splitting the reconstructed packet into a plurality of small packets, adding a Reed-Solomon code, changing the small packets into a Hash value, writing the Hash value into FLASH, performing small packet inspection, preferentially using the Reed-Solomon code for error correction if the small packets fail to inspect the small packets, and re-sending the small packets if the small packets cannot perform error correction. And after all the small packets are successfully written and verified, a complete reconstruction packet is reformed, final verification is carried out, and a reconstruction request is sent to the satellite-borne software after successful verification. And the satellite-borne software monitors the reconstruction process, counts and analyzes the verification failure frequency of the packets in the data frame, and timely updates a detailed report of the step into the database every time the step is carried out, and compares the detailed report with a final report. According to the method, software of the FPGA on the satellite can be upgraded and automatically checked, potential vulnerabilities and errors of the FPGA can be repaired, and the reliability and task execution capability of the satellite can be obviously enhanced.
