Comparative analysis of application of various filters in problem of filtering measurement disturbances of sensors in SINS

This paper considers a strapdown inertial navigation system with the measurement unit that includes three channels for apparent acceleration sensors and three channels for angular rate sensors with mutually orthogonal emplacement. The measurement information of the sensors of the strapdown measurement unit includes random errors conditioned by both exogenous factors and endogenous measurement noises that bring errors to the solution of the navigation problem and influence the navigation accuracy negatively. The goal of the paper is to filter the random disturbances conditioned by the external factors and select the useful signal from the measurement information to decrease the navigation errors.
