Instrument image

The main objective of EGG is to measure the three components of the GGT (Gravity-Gradient Tensor). The EGG instrument, designed and developed at ONERA (Office National d'Etudes et de Recherches Aérospatiales) and manufactured at Thales Alenia Space, France, is based on an ambient temperature, closed loop, capacitive accelerometer concept.

Three-axis diagonal gradiometer, based on three pairs ofelectrostatic servo-controlled accelerometers.
