北斗三号新体制信号数据质量分析与接收机性能评估

New Signal Data Quality Analysis and Receiver Performance Evaluation of BDS-3

本文主要对三种不同北斗三号接收机及其新体制信号从完整性、多路径效应、周跳比、信噪比等数据质量指标以及零基线方面进行分析评估,结果表明:北斗三号新体制信号数据质量整体较好;在B2a频点,接收机之间的一致性较高,B1C频点各家接收机还需要在性能方面进一步提升。

This paper mainly analyzes and evaluates the three BDS-3 receivers and their new system signals from data quality such as integrity, multipath effect, cycle slip ratio, signal-to-noise ratio, and zero baseline tests. The results show that the new signal data of the BDS-3 is qualified. The consistency between receivers is high at the B2 a frequency, and the receivers at the B1 C frequency need further improvement.
