摘要
简要介绍了ＧＰＳ相位平滑伪距的原理，提出了用两个载波在两个历元的相位观测量的双差来消除相位周跳，并进一步对两个载波的码伪距差进行平滑，对实际数据进行处理的结果表明了这种算法改进了双频码伪距差的测量精度。
The principle of phase smooth pseudorange is concisely introduced out in this paper. A double difference treatment of phase observables of two carriers at different epochs is provided for eliminating cycle slips and smoothing the code pseudorange difference of two carriers. The results of the practical data processing show that this algorithm improves the measurement accuracy of code psedorange difference for two frequencies.
