Abstract

This paper presents the results of recent improvements of the primary low-frequency accelerometer calibration system at INMETRO. The interferometric system was upgraded, a new software developed and the sine- approximation method was implemented. This new system allows the calibration of the complex sensitivity of accelerometers from 0,2 Hz to 100 Hz with reduced uncertainty.
