Utilization of Analytical Methods for Orbit Determination in High Accuracy Geodetic Positioning.
Abstract
The technique developed by Georgiev (1979) to permit highly accurate (0.7-2-m) forecasting of satellite positions over intervals of 2-5 days is described and demonstrated. The technique determines the intermediate orbit analytically, estimates the perturbations due to gravitational and nongravitational effects by the numerical procedure of Everhardt, and solves the resulting problem by the generalized method of two fixed centers (Aksenov, 1977). Sample results are presented in tables and graphs and discussed in terms of zonal, tesseral, and sectorial harmonics and atmospheric effects (important at altitudes up to 1200 km). The accuracy of the method is shown to be excellent, even when the flattening of earth is taken into account.
