BDS三频与双频模糊度解算性能分析

Performance Analysis of BDS Triple-frequency and Dual-frequency Ambiguity Resolution

摘要: 全球导航卫星系统(GNSS)已进入多频多系统时代。针对两条短基线,对比分析BDS三频与BDS／GPS三频对于BDS双频与BDS／GPS双频在模糊度固定率、成功率及定位精度等方面的改善情况。结果表明，BDS三频与BDS／GPS三频可有效提高BDS双频与BDS／GPS双频的固定率和成功率,但BDS三频与BDS／GPS三频对于BDS双频与BDS／GPS双频的定位精度基本上没有改善。

Abstract: The global navigation satellite system (GNSS) has entered the age of multisystem. In terms of the two short baselines, compared to BDS dual-frequenc and BDS／GPS dual-frequency,BDS triple-frequency and BDS／GPS triple-frequency are analysed in the ambiguity fixed rate, success rate and positioning accuracy.The results showed that BDS triple-frequency and BDS／GPS triple
