ESTIMATION OF ATTITUDE AND ANGULAR VELOCITY OF A SATELLITE BASED ON THE USE OF ONLY OPTICAL SENSORS

The invention concerns a method for estimating the angular velocity (and, preferably, also the attitude) of a space platform (for example, a satellite, a space vehicle, or a space station) using only the information provided by one or more optical sensors, such as one or more star trackers, one or more colour and/or black and white cameras or video cameras, one of more infrared sensors, etc.
