Abstract
To know the influence of deterministic system error to navigation system well, so the precision index of gyroscopes and accelerometers, which are the main components of rate azimuth platform inertial navigation system, and initial calibration precision, can be put forward. Based on the error equations, the characteristic equation of rate azimuth platform inertial system is established, and the solutions of the error equation under static state are obtained with analytical method, and the system error characteristics caused by the accelerometer drifts are analyzed.
