In this paper, an improved unequal-interval federated filter algorithm is proposed for the integrated navigation registration process, which can solve the asynchronous information problem and the engineering problem under large multiplier measurement period for the traditional unequal-interval federated filter algorithm. By introducing fusion information, the applicability and practicability of the algorithm are expanded, and the engineering application of the algorithm is improved. The simulation results prove that the improved unequal-interval federated filter algorithm can expand the selection of fusion moments and avoid the interrupt zone effectively, which shown a better result compared with the traditional method.
