FREQUENCY DOMAIN ANALYSIS FOR RLG SYSTEM DESIGN

Peer Reviewed

Abstract: The performance of a dithered ring laser gyro on a laboratory test bench can vary significantly from its performance in a three-axis inertial navigation system. Dynamic interactions between the sensors can create unacceptable error drift rates, as well as physically influencing other instrumentation. Using frequency domain analysis methods the engineer can determine the sources of these interactions and the magnitude of their contributions to system error. In this paper we construct the frequency model and then use it to determine the effects of physical dither on a three axis RLG system.
