| Summary: | 碩士 === 國立成功大學 === 測量工程學系碩博士班 === 90 === One of the primary international geodetic issue in the recent years is the study of the airborne gravimetry by using INS/GPS data . Quick measurements of gravity over wide areas and no terrain limit are the superiority of the airborne gravimetry .
In the study , a 1.5 km × 1.5 km test area of the airborne gravimetry by the INS/GPS data is designed . The flight plain was a double–strip in the sourth–northern and east–western direction . The gravity is estimated by the direct difference approach . The results of the experiment have shown that the internal precision of the estimated gravity is within , and the external precision about.
