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