Abstract:

This report contains a brief summary of photoelectric range detection, photographic direction detection, and design studies made for a geodetic laser system. It appears feasible to measure the displacement between a ground-based ruby laser system and a satellite equipped with retrodirective reflector arrays such as those on the Explorer and Geos satellites to an accuracy of 2 arc-seconds in direction and less than 10 meters in range at slant ranges of over 2000 km, using essentially state-of-the-art equipment described herein and in the references. The probability of detection is expected to be greater than 90 without optical tracking, if the direction is known in advance to within approximately 2 arc-minutes and the range to within approximately 1 km.
