在GPS载波相位差分定位的过程中,整周模糊度解算的准确性决定了定位的精度。由于在短历元内位置精度因子变化缓慢，导致整周模糊度的求解困难。量子测距是近几年来发展起来的新型高精度测距技术，采用量子高精度测距辅助整周模糊度的求解方法，可以明显提高定位精度。数学分析和仿真结果验证了该方法的准确性和有效性。

In measurement using GPS carrier phasethe positioning accuracy is determined by the accuracy of integer ambiguity resolution.It is well-known that the integer ambiguity can hardly be precisely resolved because of the small change of Position Dilution of Precision (PDOP) within a few observation epochs.Quantum ranging is a highly accurate positioning technology developed newly in recent years.A resolution method of integer ambiguity based on quantum ranging was proposed in this paperwhich can improve positioning precision obviously.Mathematical analysis and simulation results demonstrated the accuracy and effectiveness of the method.
