一种GNSS监测站选址模糊综合评价方法
|
摘要
全球导航卫星系统(GNSS)监测站位置布设直接影响导航系统的服务质量,因此监测站选址在GNSS系统建设过程中尤为重要。从视场、电磁干扰、多路径干扰、精度因子(DOP)值、电离层格网可用度、气象环境地质条件、政治军事安全、工作环境等因素对影响监测站选址进行了全面分析,并提出了一种"硬判决-软判决"相结合的模糊综合评价监测站选址方法。"北斗"卫星导航系统(BDS)监测站选址评估实例表明,该方法达到了监测站选址高效、精确的评估效果。
The deployment of Global Navigation Satellite System( GNSS) monitoring station would directly impact the service quality,so it is an important part in construction of GNSS. Based on the full analysis of the factors influencing the address choosing of monitoring station,such as visual field,electromagnetic interference,multi-path interference,dilution of precision( DOP),ionosphere availability,meteorology environment and geological condition,politics and military safety,working environment,a fuzzy synthetic evaluation method of "hard decision-soft decision"for the address choosing is put forward. The example of evaluation of address choosing of Beidou Satellite Navigation System( BDS) monitoring station shows this method can provide high-efficiency and accurate evaluation result for address choosing of monitoring station.
