Real-time Smoothing Algorithm for High-frequency Measurement and Control Target Attitude Based on Least Square Fitting of Orthogonal Set

Real-time smoothing of high-frequency measurement and control target attitude data is one of the hotspots of application research for ground command and control display system. This paper analyzes the main problems of the existing attitude smoothing algorithm, and proposes and implements the high-frequency measurement and control target attitude smoothing algorithm based on the least squares fitting of orthogonal set, and carries out algorithm verification analysis for UAV monitoring applications.
