Abstract : Mass attraction is used as an acceleration input to calibrate an accelerometer. The calibration has been carried out in the laboratory for an electrostatic suspended single-axis accelerometer (MESA) with a variable mass attraction. The tilting of the test pad was avoided by a vertical movement of the attracting mass and always checked by a very sensitive tiltmeter. The mass attraction input to the accelerometer was a sine wave with the amplitude of 23 x 10 to the minus 9th power g. The response of the accelerometer to this acceleration input by mass attraction was obtained by computer data reduction. The results of the experiments agree with the scale factor of the accelerometer for higher acceleration inputs. Application of the mass attraction principle as a calibration method of accelerometers for very low accelerations in orbit is proposed. (Author)
