Claim 7:
8. Method for estimating an angular velocity and an attitude of a space platform equipped with at least one optical sensor, comprising:
k1) carrying out the method claimed in claim 1, thereby obtaining the angular velocity estimate related to the first time instant;
k2) estimating an attitude of the space platform based on the first and second images acquired, thereby obtaining an attitude estimate related to the first time instant; and
k3) inputting the angular velocity and attitude estimates into a predefined Kalman filter configured to correct said angular velocity and attitude estimates, thereby obtaining refined angular velocity and attitude estimates related to the first time instant; wherein said predefined Kalman filter is configured to correct said angular velocity and attitude estimates by applying a predefined kinematic model to a refined attitude estimate obtained for a third time instant prior to said first time instant.
