Derivation of gravity anomalies from airborne gravimeter and IMU recordings-Validation with regional analytic models using ground and satellite gravity data

To verify the airborne gravity results, ground-based and satellite-derived gravity data have been used to compute local analytical gravity field models in a new methodological approach that allows the calculation of gravity anomalies at flight altitudes. For the most part there is a good agreement between the INS-airborne-derived and the independently modelled gravity anomalies, yielding best results of about 3.5 mgal RMS.
