Abstract :
Two of NASA´s Deep Space Network (DSN) 70-meter reflectors were measured using a Leica TDM-5000 theodolite. The main reflector surface was measured at five elevation angles, so that a gravity-deformation model could be derived that described the main-reflector distortions over the entire range of elevation angles. The report describes the measurement equipment and accuracy, and the results derived from the data.
