EGG
Definition
- The EGG (Electrostatic Gravity Gradiometer)has a double role. It is providing the gravity gradient measurements and it is also used as a main sensor in the DFACS. If this common mode acceleration in flight direction is not zero, the DFACS will respond by either increasing or decreasing the ion engine thrust to maintain the spacecraft in near-freefall conditions
