Technology for Automated Iterative Calibration of FOG-based SINS on a Three-Axis Motion Simulator

The methodology of calibrating a strapdown inertial navigation system (SINS) on a three-axis motion simulator is described. SINS is considered on the basis of serial fiber-optic gyroscopes (FOG) and pendulum accelerometers. The mathematical relations connect output signals of sensors with their main errors. The factory test results of SINS developed at the Research and Production Enterprise Hartron-Arkos, Ltd are presented.
