Abstract:

An evaluation and comparative analysis of several basic tracking techniques were recently conducted. The evaluation considered the use of various tracking systems in tracking and guiding satellite and lunar spacecraft in terms of 1 tracking accuracy required 2 feasibility of establishing a configuration to meet accuracy requirements 3 operational, functional, and physical attributes of such a tracking configuration, and 4 cost to produce the tracking system. The configurations of interest are 1 a single antenna tracker with a precision pedestal for angle measurements 2 a tracker with baseline antennas for angle and angular rate measurements and 3 multiple installations of single antenna trackers integrated into a range-only system. The tracking techniques of interest are 1 range measurement by pulse 2 range measurement by cw 3 angle measurement by precision pedestal 4 angle measurement by interferometer baseline and 5 position measurement by multiple ranging. A large-scale digital computer was programmed to simulate tracking of the missions with the configurations mentioned. The earth-based tracking system selected PROCTOR, a Precise Range Only Cislunar Tracking and Orbit Reduction System. Author
