A Synopsis of Field Test Results from the Gravity Gradiometer Survey System

Abstract

The Gravity Gradiometer Survey System (GGSS) has successfully collected data in both airborne and surface vehicle tests. The GGSS navigation system has demonstrated high accuracy and reliability for both the GPS-aiding and fifth-wheel aiding mechanizations. Track-to-track rms repeatability of the gravity disturbance estimates from the surface tests ranged from 2 to 3 mgal for tiepoints about 50 km apart. Comparison of airborne results with truth data yields rms discrepancies less than 5 mgal based on single-track analysis and tiepoint spacing of about 90 km, and less than 2 mgal for multi-track analysis and tiepoints about 80 km apart. Based on these test results, the GGSS offers a significant capability to perform full gravity vector surveys in a timely and economical manner. Keywords: Geodesy; Gravity; Gravity gradiometer; Gravity surveying.
