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)
