LOW FREQUENCY ACCELEROMETER CALIBRATION CHALLENGES, ANALYSIS AND NEW DEVELOPMENTS

Mark I. Schiefer, Naveen Garg

Abstract

Low Frequency accelerometer calibration is generally time consuming and requires special considerations and excitation techniques. A new class of reference sensor for use in low frequency accelerometer calibration is introduced. This paper also outlines challenges of low frequency calibration and details principal sources of error. New developments in low frequency accelerometer calibration excitation technology are introduced. Comparison to manufacturers primary calibration of an artifact as well as comparison to primary means is presented.
