| Abstract: | In order to meet the needs of development of high-precision airborne gravimeter,the sub-index design and analysis of highprecision airborne gravimeter were carried out,which provided the basis for the design of high-precision airborne gravimeter system.Based on the mathematical model of airborne gravimetry,this paper summarizes the main errors affecting airborne gravimetry,uses the theoretical model formula,deduces the error models of various influencing factors,and carries out the analysis and study of various errors,and sets reasonable sub-index by combining the relevant theoretical formula of airborne gravimetry. Accuracy can effectively control the sub item errors and ensure the accuracy of airborne gravity measurement is better than 0.6×10-5 m/s2. |
