摘要
GNSS伪距差分定位是一种能够获取较高导航定位测量精度的卫星导航定位方法,但是,它的设备较复杂,用户不仅需要使用一台GNSS信号接收机,而且需要设置提供DGNSS改正数据的基准站及其一台GNSS信号接收机,以及与之匹配的DGNSS数据链,才能够实现全天候、全天时和全球性地测量运动载体的7维状态参数。本文简要地论述了GNSS差分定位的基本原理及其实现。
GNSS pseudorange differential positioning is a kind of satellite navigation/positioning methodwhich can obtain high navigation/positioning accuracy. But its equipment is more complicated, the user not onlyneeds to use a GNSS signal receiver, but also need one reference station and a GNSS signal receiver to provideDGNSS correction data. They are named as DGNSS data links. Such we can realize the all-weather, day/night andglobal measurement for motion carriers of the seven dimensional state parameters. This paper discusses briefly thebasic principle of GNSS differential positioning and its realization.
