On the Accuracy of EGM2008 with Measured Data Based on Strap-down Airborne Gravimetry

Abstract. Gravity survey is an important research topic in geophysics and geodynamics. This paper analyzes the accuracy of EGM2008, the newest Earth gravitational model, in two areas in Shandong Province of China. By comparing the gravity anomaly data from the model with those obtained by a strap-down airborne gravimeter called SGA-WZ, it shows that error accuracy between the gravity anomaly calculated from EGM2008 and the measured data in these two areas is within 2.16mGal
