Bias stability of less than 0.75 deg/hr, random walk of 0.012 deg/hr, scale factor linearity better than 45 ppm and scale factor residual over temperature (after linear fit) better than 45 ppm have been demonstrated with a medium accuracy fiber optic gyro. Based on this performance, low production cost FOG-based IMUs with bias stability of less than 1.0 deg/hr over full military environment are practical for near-future military applications. Furthermore, a model of bias errors in reasonable agreement with experiment has been developed.
