基于局域参考站网络伪距观测的钟差估计及应用
Estimation and Application of Clock Error Based on Pseudorange Observation of Regional Reference Network
摘要
Abstract
The formula by which the real-time clocks are estimated is deduced, and the model of precise point positioning is discussed based on the pseudorange observation of regional reference network. The pseudorange observation from Shanghai reference network is used to estimate clocks using the presented method. Using the estimated clocks, the data from Tongji University Station is processed in real-time point positioning mode. The real-time kinematic results indicate that the root mean square (RMS) of three directions such as the North, the East and the Up are 0.444 2, 0.522 7, 1.110 9 m,respectively.关键词
