Paper Abstract

The error model of Fiber Optic Gyro System is simpler than Mechnical gyro, Fiber Optic Gyro offer the advantage of an extremely broad bandwidth and additionally the presence of Random Walk in the output. In this paper, A Calibration Technique was developed to calibrate a fiber optic gyro strapdown inertial navigator using a low cost two-gimbal test-table. Accelerometer scale factor and bias and accelerometer and gyro misalignments are calibrated using measurements of the acceleration in the navigation frame after each rotation. A sequence of ten rotations has been chosen to stream-line the procedure. The validity of the model is tested in real fiber optic gyro system.
