Abstract

All of NASA’s Deep Space Network (DSN) 70-m 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 article describes the measurement equipment and accuracy and the results derived from the data.
