|Abstract:||This paper presents a decentralized filtering approach for dealing with the problem of reconfiguration subsequent to sensor failures in multisensor/integrated navigation systems. The filters presented in this paper are based on Covariance Intersection (CI) and its variant Bounded Covariance Inflation (BCI) and allow dealing with sensors that behave as a “black-box” and enable fusing the minimal available sensor data with the rest of the navigation system. The effectiveness of these techniques for decentralized sensor fusion is compared with other well-known federated architectures. A simulation study using a simplified heading estimation problem is used to highlight the trade-off between filter performance and design flexibility.|
