| Abstract: | We improve the accuracy of GPS mobile observation positioning using the time series of continuous observation stations within 200 km of the GPS mobile station, and discuss the reliability of GPS mobile observation results. The results show: 1) The standard deviation of velocity obtained by mobile observation decreases by 37.97% compared to continuous observation. 2) The deviation of measured value decreases by 38.9% on average after correction at TAIN and CASH sites. |
