A DIRECT DIRECTION-DOPPLER SLANT-RANGE DETERMINATION TECHNIQUE FOR ORBITING SPACE VEHICLES.

Abstract

Demands for greater accuracy in predicting positions and motions of space vehicles orbiting celestial bodies are rapidly increasing. To meet these demands, directly applicable to earth-satellites, a relatively simple, direct, and time-saving method has been developed for determining necessary slant-range values using direction and Doppler data. The method utilizes the output of optical and electromagnetic tracking techniques currently in use for calculating earth-satellite orbit predictions. A simulated trajectory, generated on a high-speed computing machine, was used to test the technique developed. Tracking data derived from this trajectory together with the check results and reference values were tabulated. (Author)
