Testing EGM08 using Czech GPS/leveling data

Original language description

The new Earth Gravitational Model 2008 (EGM08) was tested using a set of 1024 high-accuracy GPS/leveling stations in the Czech Republic. Values of height anomalies synthesized from the new model were compared with those derived by the combination of leveled Molodensky-type normal heights and GPS-based geodetic (ellipsoidal) heights. The standard deviation computed from the obtained differences was equal to 3.3 cm. For comparison purposes, the previous model EGM96 has been tested with the same data set.Compared to this model, the new gravitational model fits five times better to the GPS/leveling height anomalies.
