Abstract:

The program goal was to repair, modify, test, calibrate and prepare two Electrically Suspended Accelerometers ESA for a space flight test. Calibration data was collected with the ESA mounted in a flotation chamber which provides the means of controlling static forces in the range of 0.01 to 0.0000001 g as test input to the accelerometer. Test data was fitted to candidate math models of the ESA the models contain terms which describe the bias, scale factor and cross coupling characteristics of the accelerometer. Performance data on the instrument is presented for each of the two calibration tests. The report describes the electrical noise problem which was encountered and which affected the accelerometer calibration. A computer based simulation of the ESA was made to study its expected operation in space.
