【 摘 要 】

In view of the problem of dynamic GPS elevation anomaly control measurement, the fitting model is optimized. Under the dynamic condition of the sea, the differential GPS receiver is used to design the measurement network according to the certain route. At the same time, the high range fitting method is used to select the GPS elevation linear fitting model and the barometer level height measurement for normal high contrast compensation measurement. . The method is used to preprocess the collected data in real time, and the real time analysis and compensation of the barometer leveling data for the fitting output results can effectively realize the regional GPS elevation measurement under the sea dynamic condition.
