摘要
北斗地基导航信号网络是以伪卫星为核心技术的北斗地基增强系统，可以在北斗卫星信号受到遮挡或干扰并影响用户正常使用时为用户提供定位和授时服务。本文介绍了北斗地基导航信号网络的组成和关键技术，并使用现场实验的实测数据进行验证。实验结果表明，北斗地基导航信号网络已经可以在用户接收北斗卫星数量小于4颗时为静态用户提供良好的定位和授时服务。
BeiDou ground-based navigation signal network is a ground-based augmentation system based on pseudolite technology, which will provide positioning and timing services to users when the satellite signals are blocked or interfered. The composition and key technologies of BeiDou ground-based navigation signal network are introduced and validated with measured data from field experiment. The experiment results show that the network can provide good positioning and timing service for static users when available BeiDou satellites are less than four.
