A Seasat data arc is analyzed in order to: gain experience in computing accurate orbits from laser ranging data; assess gravity and surface force model accuracy; determine the positions of five European Doppler stations relative to a global NASA ground station coordinate solution; and study the effects of European Doppler range-rate data on the orbital solution. The PGS S3 and S4 models yield better results than GEM 9 or GEM 10B. More data must be analyzed since one arc is not representative, especially considering that orbital coverage in that arc is not good.
