Satellite navigation method for interactive multi-model UKF with self-adapting factors

The invention relates to a satellite navigation method for an interactive multi-model UKF with self-adapting factors, and belongs to the field of navigation control. The method comprises the steps that firstly, an auto-covariance matrix of a residual sequence is used as a correcting value, and a smoothing filter is designed for fusing the correcting value with the old self-adapting factor to obtain the new self-adapting factor; secondly, a covariance matrix of process noise is adjusted in real time by utilizing the self-adapting factor, and therefore positioning errors, caused by unknown noise statistics properties, in a system are effectively reduced; afterwards, a model set M is set by the adoption of the interactive multi-model (IMM) algorithm; finally, soft handover between models is achieved by adjusting model probability in real time according to measurement residual errors, so that positioning errors caused by inaccurate system models are reduced. According to the method, the positioning accuracy of a complex motor carrier in a satellite navigation system is effectively improved with models and noise statistical properties unknown.
