| Abstract: | The stability of the base station coordinates is basis of continuous peration of GPS integrated system. In this paper, the Beijing CORS base stations＇ accuracy is analyzed by GAMIT software. Analyzing the base stations＇ coordinates and velocity variation, and gives the accuracy of the statistical analysis. The result shows that the trend of coordinate component is linear, and the coordinate residual changes in random. N, E orientation accuracy is better than 2 ram, elevation direction accuracy is better than 5 mm. Base stations operate stably. |
