| Abstract: | Currently there is no consensus among scholars on the appropriate choice of gravity correction models for platform tilt in sea-borne and airborne gravimetry. In this paper, the equivalency of the three existing correction models recommended for usage are analysed theoretically and platform tilt effect is empirically evaluated. A set of airborne data from practical survey lines is used to examine and compare the numerical value of platform tilt effect of the three existing correction models. The results clearly and definitely prove our efforts, and this offers useful theoretical support for the choice of data processing steps and correction models in application of airborne gravimetry. |
