LSG flight configuration simulation

Abstract

The sensor beam of Flight Lunar Surface Gravimeter (LSG) has been centered by partially uncaging the lunar masses. In this configuration the sensor exhibits a 1. 5 Hertz oscilation. Attempts to duplicate this configuration employing the Qual LSG were unsuccessful. The beam of the Qual Model was centered employing both the mass change mechanism and the beam clamp mechanism, however, the characteristic oscillation for both conditions was approximately 17 Hertz.
