,The Use of Brown’s Lunar Theory in Lunar Satellite Perturbations by Sun and Earth, by Earth and Sun to a high degree of accuracy. The present paper describes how the first- and second-order Earth-solar changes in the elements of the selenocentric Keplerian satellite orbit are obtained by making use of Brown’s lunar theory. Values are given of the accuracy attained by comparing ch

Satellite Trajectory Determination and their Expected Errors OGO-IV, GEOS-I, important is the determination and separation of the errors caused by the tracking systems from those caused by the trajectory determination process. Only a very good understanding of this effect will lead to the required decrease of trajectory errors..In this paper, orbits from GEOS-A and OGO spac

Improved Values for the Tesseral Harmonics of the Geopotential and Station Coordinates,ystem are combined in a global solution for gravity-field parameters and station coordinates. The data base represents a significant improvement on previous work, with increased accuracy and better distribution. The gravity field is given complete to 14th degree and order, and more than 29 station n

,On the Determination of Parameters of the Earth’s Figure from Satellite Orbit Dynamics,ational potential of the Earth. If the geocentric constant is given, it is possible, using these quantities, to determine the shape of the equipotential surfaces of the external gravitational potential or of the gravity potential. To determine the dimensions of the surfaces, however, further data wo

Accuracy of Satellite Orbits Obtainable by Synchronous Satellite Tracking,nd range rate measurements by synchronous satellites. Included in the investigation are the effects of measurements noise and biases, earth based station location errors, and geopotential coefficient errors. Results are presented for each source in the form of satellite epoch element errors and posi

Resonant Satellite Geodesy by High Speed Analysis of Mean Kepler Elements,f these elements is calculated by numerical integration of their long period and secular variations..With only slowly-changing mean element coordinates being integrated, a step size of the order of an orbit revolution or more is achieved. Satellite ephemerides over 5000 revolutions are calculated in

Short Arc Optical Survey of the GEOS North American Network,e dependence of the final adjusted surveys on the adopted value of the gravitational parameter and the coordinates of the earth’s center of mass were analyzed. The results indicate that the accuracy of dynamically derived scale is dependent on the coordinates of the center of mass relative to the tr
