摘要
随着北斗三号卫星建设即将完成,北斗服务平稳过渡为由北斗三号系统为主提供。2019年12月27日B2b信号接口文件公布,公开了两种B2b信号,提供基础导航服务的B2b信号和提供精密单点定位服务的PPP-B2b信号。基于B2b信号接口控制文件,介绍了B2b信号信息结构、信息类型以及天空中卫星信号解析结果,并给出了B2b信号的定位精度结果,对天空的PPP-B2b信息进行了解析。对B2b的Q支路信号也进行了探索。
With the construction of BDS Ⅲ satellite nearing completion, Beidou service will transition smoothly to be provided mainly by BDS Ⅲ system.The B2b signal interface document was announced on December 27, 2019.B2b signals are divided into two types:B2b signal that provides basic navigation services and PPP-B2b signal that provides precise point positioning services.Based on the B2b signal interface control file, this paper introduces the B2b signal information structure, message type, and analy-sis results of satellite signals in the sky, and gives the positioning accuracy results of B2b signals.The PPP-B2b information in the sky is also analyzed.This article also explores the Q branch signal of B2b.
