摘要
在风云二号静止气象卫星中,测距分系统是地面应用系统指令与数据接收站的重要组成部分,其运行成功率及准确率影响着卫星轨道的定位精度,进而影响卫星云图的精度,对业务造成影响。统计了2014年测距分系统出现的所有故障,并使用故障树分析法对其进行分类整理,得到引起故障发生因素的权重值,然后通过2015年出现的故障对该方法进行了验证;同时,针对各故障还提出了相应的解决措施,为日常运行维护以及故障的快速处理提供借鉴,以提高风云二号测距分系统业务运行成功率,同时为风云四号测距分系统的日后运行维护积累宝贵经验。
In FY-2geostationary meteorological satellite,the ranging subsystem is an important part of the ground application system,whose success rate will affect the positioning accuracy of the satellite orbit and cause degradation of imagery resolution.This paper analyses all failures of ranging subsystem appeared in 2014,and Failure Tree Analysis was used to sort out the failures to get the failure factor weights,and then this method was verified through the failures appeared in 2015.Meanwhile,this paper also proposes corresponding solutions for each kind of failures to provide references to improve success rate of the FY-2ranging subsystem and gain valuable experience for future operation and maintenance of the future FY-4ranging subsystem.
