LAASIMT中DQM算法研究

Algorithm for DQM in LAAS IMT

数据质量监测位于LAAS完好性监测系统的前端，是一个关键环节。本文介绍了数据质量监测的方法，引入了新旧星历检测和星历一历书检测两种方法以检验GPS卫星星历的有效性。对实验数据的分析表明，上述两种方法能满足初步的数据质量监测需求。

Data quality monitoring is at the front of the LAAS Integrity Monitor Tested system, and is a very important phase. This paper introduces the methods of the data quality monitoring; include the New-Old Ephemeris Detecting Method and the Ephemeris-Almanac Detecting Method. The analysis of the real testing data shows that both of the above methods can meet the basic requirement of the data quality monitoring.
