Abstract

Differential positioning technology is used to improve positioning accuracy by eliminating the common errors with the spatial correlation between the reference station and the user station. Pseudo-range differential is the most widely used as a positioning technology. The paper details the data processing algorithm of pseudo-range differential model, followed by the simulation analysis. The results show that compared to the single-point positioning, pseudo-range differential positioning of Compass has smaller error and higher precision. In addition, with the increasing of the two receives´ distance, the error increases gradually. This is similar to GPS differential positioning theory.
