CLEM1 LUNAR GRAVITY V1.0

The gravitational signature of the Moon was determined from velocity perturbations of the Clementine spacecraft as measured from the Doppler shift of the S-band radio tracking signal. Clementine was tracked by NASA's Deep Space Network (DSN) at Goldstone, California, Canberra, Australia, Madrid, Spain, as well as by the Pomonkey, Maryland, tracking station operated by the Naval Research Laboratory. The tracking data were used to determine the Clementine orbit about the Moon, as well as the lunar gravity field [ZUBERETAL1994]. A detailed description of how the Clementine orbits were computed and an assessment of their quality can be found in [LEMOINEETAL1995B].
