卫星地面站系统软件抗衰策略研究
Study of satellite earth station system software rejuvenation.
摘要
Abstract
Satellites are increasingly widely used in military reconnaissance,resource exploration, weather forecasting,television broadcasting, communications and other important areas, so the satellite ground station system should have higher request than any ordinary sof vare system for security,reliability,survivability,error detection and recovery.Satellite systems require a high degree of real time so the satellite ground station software system is not allowed in force.However,there exists the software aging phenomenon in system which will lead to software failure.To resist software aging, this paper presents a software micro-strategy of anti-restart applications that can shorten the average recovery time(MTTR),achieving the target to improve the reliability of the system.Meantime,the microreboot strategy can track satellite altimetry and precise orbit determination of the original provision of satellite observation data.Satellite altimetry can improve the rail and the accuracy of orbit determination which has an important practical significance and the application value.关键词
