摘要

This paper is devoted to the problem of construction and experimental evaluation of the effectiveness of robust modifications of an extended Kalman filter (EKF)for onboard computers. The proposed solution of the above problem relies on numerically stable U-D modifications of the EKF and on a unified technological process (UTP) for their flight and ground development. Procedures for integration, in the structure of the U-D filter, of the loops intended for robust and adaptive protection of the estimates from their divergence are justified. Stages of the UTP are revealed. The results of flight experiments are given, which corroborate the effectiveness of the application of U-D modifications of the EKF for estimating the errors of integrated navigation systems.
