摘　　要：本文针对载波相位平滑伪距差分技术在高精度测量的应用,推导了单频和双频载波相位平滑伪距的原理,分别给出了单频和双频载波相位平滑伪距差分模型。通过试验分析,比较了单频和双频差分导航定位精度,分析了双频载波相位平滑伪距差分定位的优点,且其差分定位精度可达亚米级。According to the differential technology of carrier phase smoothed pseudo-range in the application of high-precision measurements, the principle of single-frequency and dual-frequency carrier phase smoothed pseudo-range are derived in this article, and then the model of those are given. The precision of single-frequency and dual-frequency differential navigation positioning are compared and the advantages of dual-frequency carrier phase smoothed pseudo-range positioning are analyzed. The experiment shows that the differential position precision can obtain the level of sub-meter.
