摘要：
Conditions on the optimality of the introduction of preprocessed attitude estimates in the Kalman filter are developed. The results are applied to lunar descent to landing navigation. The attitude estimate is obtained with the Davenport q-method and a modified measurement model. Together with the attitude estimate, the preprocessor passes to the Kalman filter the estimation error covariance.
