A Robust Algorithm of Carrier Phase Smoothed Pseudo Range in Real Time Location Systems

针对可能出现的伪距突发错误及载波周跳的问题,研究一种应用于低动态区域实时定位系统的鲁棒载波相位平滑伪距算法。仿真结果表明,方法可以在一定程度上减小由于伪距突发错误与周跳所引起的测距误差,进而提高定位精度。

Considering the burst error of pseudo range and carrier cycle slip,a robust carrier phase smoothed pseudo range algorithm is developed for the low dynamic system.Simulation results reveal that with the proposed algorithm the error caused by burst error of pseudo range and carrier cycle slip is reduced and the location precision is improved.
