Scientific paper

The paper further develops the comparison of lumped coefficients, observed from resonant perturbations of satellite orbits, or reconstituted from various resonant solutions for the individual harmonic coefficients, or from harmonic coefficients in the Earth gravity field models (EMs). If these types of information are mutually independent, the accuracy of the EMs (for a particular order of harmonics) can be tested. The tests can be prepared for arbitrary orbital inclination I and selected order m, using "fictitious" satellite orbits. Numerical results are now available for 30 ≤ I ≤ 140°, 2 ≤ m ≤ 15 plus m = 30. They are valid for circular (q = 0) as well as eccentric (q = 1) orbits.
