GPS接收机伪距测量方法研究

Study on GPS Receiver's Pseudo Range Measurement

介绍了一种高精度伪距测量方法。该方法通过位同步、帧同步、码捕获、码跟踪算法以及载波辅助技术等方法来获取高精度伪距测量值。重点研究了秒模糊度、毫秒模糊度和毫秒内的精度测量方法,得到了通过设置码跟踪环的相关间隔来设置其测量精度的方法。实验结果验证了算法的可行性。

A new high--precision pseudo range measurement method is presented, the precision is achieved by bit synchronization, frame synchronization , code-track algorithms and carrier aided technique. The measurement method of second,millisecond and inside a millisecond ambiguities is discussed. The experiments demonstrated the effectiveness of the proposed algorithms.
