It is of great significance to study the data-processing methods of airborne gravity survey,improve the accuracy of data processing and catch up with the advanced world level. In this paper,based on the domestic three-axis stabilized platform airborne gravity measurement system,the authors carried out the research on data processing methods and corresponding software development of airborne gravity measurement and realized the Kalman smoothing algorithm suitable for the stabilized platform airborne gravity data. The platform airborne gravity anomaly was solved for the first time in China. The internal coincidence accuracy reached 0.590× 10~(-5) m/s~2,the external coincidence (GT airborne gravity measuring system) accuracy reached 0.581×10~(-5) m/s~2,and the accuracy of data processing was up to the international advanced level. The results show that the data processing method is feasible,has high precision,and can improve the data-processing technology of airborne gravity survey in China.
