This report covers the results of a tracking feasibility study, transponder design study and prototype fabrication of a lunar transponder, and a lunar impact-point marker study. see AD-603 272. During the tracking study both one 1 and four 4 station global configurations were considered utilizing basic GLOTRAC Ground Stations with modifications. Atmospheric effects were considered and numerical analysis was undertaken to determine ultimate system accuracies. The transponder study included electronic circuit design, advanced microwave techniques, and special packaging techniques. A breadboard and prototype transponder was fabricated and tested. The prototype transponder was designed to be capable of operation after current state-of-the-art conception of a hard lunar impact. The impact marker study investigated both passive and active techniques. Author
