<p>System for determining the angular spin position of an object (1) spinning about an axis situated within certain limits near the surface (2) of a celestial body. The system is provided with means (4, 5, 6) for generating at least one carrier wave (7, 8) reaching as far as the surroundings of the object (1) and up to and interfering with the said surface (2). The system is further provided with directional receiving antenna means (16) fitted to the object (1) and a receiving system (19) linked thereto for determining the angular spin position of the object (1) with respect to the surface (2) on the basis of the angular spin position of the object (1) with respect to the polarisation direction of the carrier wave (7, 8).</p> |
