基于GPS的短基线定向测量及精度分析

GPS-BASED ORIENTATION DETERMINATION OF SHORT BASELINE AND ITS PRECISION ANALYSIS

介绍了利用GPS载波相位测量技术进行短基线定向的基本方法,推导了估计GPS短基线定向的精度公式,得到了对于边长400-700 m的基线可以达到±（1″-2″）的方位精度。

The method for orientation determination of short baseline based on GPS carrier phase is introduced, and the precision estimation of azimuth is ayart, then several shortline＇s azimuth are computed to make a comparing with astronomical azimuth, and a precision ±（1″-2″） with the length between 400 700 m is obtained.
