卫星定位信号载波相位测量技术

Carrier Phase Measurement Technology of Satellite Positioning Signal

卫星定位系统通过多颗定位卫星与接收机间的距离来计算接收机的真实位置坐标信息,常用的测距方法有伪距测量和载波相位测量。该文以GPS定位系统为例,介绍了卫星信号的载波相位的含义及其测量技术,并针对载波相位测量技术周期数模糊问题,分析说明了载波相位差分技术的优点及不足。

The distance between the positioning satellites and a receiver are used to generate the actual position information of a receiver in a satellite based positioning system, and the main two methods are the pseudo range measurement and carrier phase measurement, respectively. Take the global positioning system(GPS) as example, this paper introduces the definition of the carrier phase of the satellite positioning signal and its related measurement technology. To solve the periodic resolution ambiguity problem, real time kinematic technology and its performance are also studied in this paper.
