| Summary: | 碩士 === 國立成功大學 === 測量工程學系碩博士班 === 92 === Quick measurements of gravity over wide areas and no terrain limit are the superiority of the airborne gravimetry . The accuracy and error model of airborne gravity affected by methods of determining airborne gravity .
In the study , Kalman filter for determining airborne gravity disturbance vectors from airborne GPS/INS measurement data is applied , and furthermore , Least Squares Collocation is used to improve the accuracy . The results of the experiments have shown that the internal precision of the estimated gravity is about ±4mgal, and the external precision about ±8mgal.
