摘要: In this paper, a improved inertial frame alignment algorithm is proposed, which significantly improves the accuracy and time cost of traditional coarse algorithm. Firstly, dimensionality reduction Gauss-Hermite filter employed in horizontal fine phase. Secondly, according to feature gravity, that components gravity projected reference zero, projection body coordinate could be calculated easily after alignment. Thirdly, weighted smoothing used adjust obtained phase, then initial accomplished. The simulation results show can greatly reduced. And fast achieve medium within 6 minutes. That meets requirement marine SINS.
