For the sake of combination that keep integrated navigation partial filter function variety from integrating the problem adjust the information allotment, the paper analyzed in association with consults in the Kalman filter a calculate way the characteristics between system, main filter and partial filter, give the integrated navigation system of in association with the describes of federated filter algorithm in a specific way, putting forward a kind of according to the broad sense characteristic value resolves of from orientation information allotment strategy, that result expresses, adopting the integrated navigation information fusion technique to practice in the engineering top assuredness can resolve to integrated navigation the partial filter function to adjust the problem that information assign the strategy at any time according to the combination.
