Abstract

The relative positioning precision based on GPS carrier-phase measuring can achieve minimeter level. Also, the high precision can be obtained in measuring direction with it. This paper introduces firstly the theory of positioning and orientating using double-difference carrier-phase and the transformation coordinate system . Secondly the baseline vector is calculated using least-squares method. Finally, algorithms for fast solving integer ambiguity are analyzed in detail especially. After tests repeatedly, its directional precision is 2.0 mil.
