北斗三频与双频相对定位性能分析

摘要

对北斗三频与双频相对定位的性能进行分析。鉴于目前对北斗三频相对于双频的优势分析较少，本文利用北斗及G PS实测数据在定位精度与质量上，分析对比了二者的性能且对北斗频率的变化对定位产生的影响进行了分析。同时区分GEO、IGSO、M EO不同类型卫星对整周模糊度解算的影响进行了实验分析。%To analyze the performance of relative positioning with BeiDou triple‐frequen‐cy and dual‐frequency data .Given the current BeiDou triple‐frequencywith respect to the du‐al‐frequency advantages of less analysis ,analyzed the performance of the two and the impact of the positioning with BeiDou frequency changed with real BeiDou and GPS observations .At the same time ,the comparison of variousinfluenceon ambiguity resolution between the differ‐ent types of satellitesGeostationary Orbit (GEO ) ,Inclined Geosynchronous Orbit (IGSO ) , and Medium Earth Orbit (MEO) was also conduct .
