基于预报的实时卫星钟差完好性监测算法比较

摘要

T he model of satellite clock error w as established based on historical data ,a real‐time integrity monitoring algorithm of satellite clock was proposed ,and comparative a‐nalysis the effect of integrity monitoring by using the least squares algorithm and forgetting factor least squares algorithm .The results showed that :forgetting factor least squares algo‐rithm is better than the least‐squares algorithm to monitor .%利用钟差历史数据建立卫星钟差模型，提出了基于预报钟差的卫星钟差完好性监测算法，并对比分析了采用最小二乘算法和遗忘因子最小二乘算法对钟差异常监测的效果，结果表明：遗忘因子最小二乘算法监测效果明显优于最小二乘算法。
