An alternate tracking approach has been formulated which utilizes a combination of the autotracking technique and the open-loop or pointing technique. The two configurations are combined to produce a 'hybrid loop' configuration which eliminates the problems associated with the noise jitter/lag error conflict as well as the error associated with the completely open loop pointing technique. A complete serve control system was analyzed, designed, built, and tested in order to verify the technical feasibility of the hybrid approach. A breadboard antenna was mounted upon a platform which could move to simulate ship's motion. Platform static and platform dynamic tests were run using the hybrid tracking approach as well as the pointing only approach. The results for each implementation were compared in order to measure the improvement obtained with the hybrid configuration. Preliminary results indicate the hybrid configuration as a feasible solution to the tracking problem associated with narrow-beam antennas on freely-moving platforms.
