1. System (3, 4) for orienting an electromagnetic receiver (20), in a location (1) where the signals from satellite navigation systems cannot be received, relative to an emission beacon (4) that is disposed around said location (1), outside of said location,
wherein said emission beacon (4) comprises: at least two emitting current loops (6.1, 6.2, 6.3) that are mutually orthogonal and are capable of emitting electromagnetic waves (5.1, 5.2, 5.3), and
means (7) for sequentially supplying power to said emitting current loops (6.1, 6.2, 6.3), wherein the electromagnetic receiver (20) is associated with means (30) for processing the electromagnetic waves (5.1. 5.2, 5.3) that are emitted by the emitting current loops (6.1, 6.2, 6.3) and received by said electromagnetic receiver (20), said processing means (30) being capable of: correlating the difference between the angles that are formed by said electromagnetic waves (5.1, 5.2, 5.3), at the electromagnetic receiver (20), with the direction of said receiver (20) relative to the emission beacon (4), and determining the orientation of the electromagnetic receiver (20) relative to the emission beacon (4) on the basis of said correlation. |
