Abstract

This paper firstly discussed on the mathematical model of GPS pseudo-range positioning for code observations. Based on IGS tracking data, taking the L2C code and L1 C/A code observations that can be viewed constantly in one hour from 5~6 GPS modernization satellites as the analysis object, the satellites were tracked by IGS tracking stations that can capture L2C code observation, such as WUHN station, KIT3 station and SUTM station. Then compare the result of surveying and positioning between L2C code and L1 C/A code. It shows the main difference that C/A code is slightly better in x- and H-directions but worse than L2C code in y-direction, these was probably associated with the internal characteristics of ranging codes.
