Incoordinate Interval Federated Filtering of Integrated Navigation
Yufei Wang · Journal of Chinese Inertial Technology · 2002
Different data update rate of various navigation devices in integrated navigation systemmay not make the federated filter infuse local information at every cycles, hence may lossinformation and induce factitious errors. An incoordinate interval federated filtering algorithm is proposed in this paper, which may optimally integrate measurements of different update rate, and the proving of its optimality is also given. The proposed algorithm can realize the optimal fusion ofincoordinate interval information through the setup of different computing and fusion periods.
