Random weighting filtering algorithm and its application in SINS/SAR Integrated Navigation System

Strap-down Inertial Navigation System (SINS) is a typical navigation system with strong independence. To improve its performance in space, time and precision, a new Random Weighting Filtering algorithm (RWF) is proposed in this paper which adopts random weighting method. By studying its application in SINS/SAR Integrated Navigation System and comparing with other algorithms, it can be seen from the experiments that the proposed Random Weighting Filtering algorithm could significantly improve the performance of SINS/SAR Integrated Navigation System.
