CHAMP and GRACE global geopotential models EIGEN-3p, EIGEN-GRACE01S, GGM01S and GGM01C are compared with terrestrial gravity field data in Hungary. The methods used for comparison were direct comparison with gravity anomalies and the reference geoid solution method. We used free-air gravity anomalies interpolated on a 1' × 1.5' grid covering Hungary. In the second method these geopotential models were used to compute gravimetric geoid solutions and the results were compared with GPS/leveling data from EUVN campaign and the Hungarian GPS network.
