<p>A system for determining the angular spin position of a second object (1) spinning about an axis. A first object (7) emits electromagnetic waves. The second object (1) is provided with directional receiving antenna means (10) and with a receiving system (13) which, using the receiving antenna means (10), process in combination the carrier waves received to obtain said angular spin position. The received signals comprise at least one polarised first carrier wave and a second carrier wave which comprises phase information of the first carrier wave.</p> |
