Software System Design and Implementation of Remote Sensing SAR Satellite

Software system of remote sensing SAR satellite is designed by structured method of decomposing the requirements of the satellite capability enhancement layer by layer, so as to meet the requirements. The user-friendliness of the software system is realized by abstracting the physical realization of the satellite, isolating the non-core functions and information, and optimizing the operation mode. The design of software system resource optimization is realized by optimizing computing resources, storage resources, information channel resources, and operation mode. The software system robustness design is realized through data security control, interface fault tolerance, fault detection isolation and reconfiguration, and on-orbit reconstruction. According to the results of satellite on orbit, the software system design meets the requirements, and the reliability of satellite on orbit and the user-friendliness operation have been effectively improved.
