Abstract: | This paper studies the technique of the relative positioning based on the measurements of GPS carrier phase,using the algorithm of combination of least-squares method and fast ambiguity resolution to search of integer ambiguity,and discuss the major factors influenceing positioning accuracy.At last a static experiments is carried out and the results show that the resulting positioning accuracy is below 1cm under the condition of short baseline by using this method. |
