Abstract
The invention described here concerns the use of GPS (Global Positioning System) interferometry, or any similar satellite constellation, to estimate the attitude of a vehicle, and is particularly suited for LEO (Low Earth Orbit) satellites. The invention is based on a system of gyroscopic and interferometric sensors and a piece of software to process the data received by such sensors. The invention can be applied to any type of vehicle (terrestrial, naval, aircraft or spacecraft) to determine the attitude of the vehicle with respect to an inertial reference system.
