Abstract : Bias errors associated with the three-axis electrically supported accelerometer (ESA) are investigated. This investigation uses the recently developed flotation technique in which the lg laboratory background and associated seismic variations are attenuated to a low level (as much as 10 to the -7th power below their original magnitude) by floating the instrument proof mass in a dense gas (SF6). An analysis of calibration errors associated with the flotation technique is presented. (Author)
