Abstract

Abstract: Aiming at the demand for the on-orbit maintenance, a new simulation technique was developed. The simulation contained on-orbit failures reproduction and location, onboard software upgrade and patch. A virtual technology was used to construct all virtual hardware environment, imitate their function and simulate the real satellite control system. This all-digital platform implemented precise multi-type faults injection, internal state monitoring and data stream intervention very well. So it could roundly simulate and test the software upgrade of the attitude and orbit control systems. It could also be used in the high-fidelity simulation of satellite-ground synchronous operation and maintenance, especially it is very helpful to improve the reliability of a satellite and prolong its life.

Key words: virtual technology, all-digital platform, attitude and orbit control, on-orbit maintenance, synchronous operation
