摘要
星基增强系统(SBAS)是北斗三代卫星导航系统的重要组成部分。首先介绍了北斗SBAS的基本情况,接着介绍了北斗SBAS的终端定位的实现及相关算法。最后对终端设备使用抗干扰天线在无干扰和有干扰状态下进行测试,结果表明北斗SBAS的精度均优于单点定位精度。
Satellite Based Augmentation System(SBAS) is an important part of Beidou System(BDS).First of all,the basic composition of BDS SBAS is introduced.Then,the complete and correlation algorithm is introduced.Finally,the experiment of positioning accuracy of BDS SBAS using anti-interference antenna which with and without interference is done.The result shows that the positioning accuracy of BDS SBAS is obviously better than positioning.
