“…Besides, the number of pulses outputted by the gyro under significant heading change differs greatly from that computed based on the calibration results under slight heading change. These phenomena are referred to as the course effect [8]. Repeated experiments have shown that new drift occurs under additional disturbance torque.…”

This paper attempts to improve the accuracy of navigation accuracy evaluation of inertial navigation system (INS). Firstly, the course effect error of the INS was analyzed in details. Then, the errors of inertial devices like gyro and accelerometer were modelled separately. Based on these models, the author simulated how the course effect error and the second-order errors related to the specific force (SF2Es) affect the speed error, position error and attitude error of the INS, under two trajectory conditions. Based on the solution of the models, a navigation accuracy evaluation software was developed, which can evaluate one or more INSs at the same time. The research findings lay the theoretical basis for INS navigation accuracy evaluation.
