Accuracy of Satellite Orbits Obtainable by Synchronous Satellite Tracking
A comprehensive error analysis is made of the accuracy of satellite orbits (both low altitude and highly eccentric) which can be obtained from range and 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 position errors propagated along the trajectory for a nominal three day tracking period. All correlations are fully accounted for between the effects of the various error sources on epoch elements and on trajectory. All analyses are performed for tracking by both a single synchronous satellite and by three synchronous satellites spaced 120° apart.
