An Analytical Method of Orbit Determination

  • An analytical method of the orbit improvement for artificial satellits is presented.In the perturbation calculation, the perturbations including long periodical terms of J2, J3 and J4 due to non-spherical gravity field on Earth, the short term of J2, the long term of atmospheric drag, the solar radiation pressure and lunisolar effects are considered.The arithmetic of differential orbit improvement is used in the corrections estimated of initial elements.After constringency, the root-mean square error is about 5" and more than 80% data are used.
