| Abstract: | The capacitance sensing and feedback control combination algorithm for redundant design based on eight pair capacitance electrodes, which is employed to the electrostatic suspension accelerometers in the GOCE gravity gradient satellite, is discussed, and then the pre proposal on failure recovery for some possible faults of an accelerometer in orbit is formulated.Finally, its improvement reliability compared to similar accelerometers but with six pair electrodes for the CHAMP and the GRACE missions is presented. |
| Keywords: | electrostatic suspension accelerometer satellite gravimetry reliability redundancy design gravity-gradient satellite |
