<p>The device comprises a) two transmitters (16, 17) of two radioelectric frequencies, whereby said transmitters are connected to a moving object and b) reception bases (B3, B4, B1, B2) that are sensitive to each radioelectric frequency and are individually provided with a pair of antennae disposed in fixed positions at a predetermined distance (L) from each other in order to deliver electric signals that are representative of the radioelectric signals received, in addition to comprising inferometric means that are supplied with said electric signals in order to provide continuous measurement of the current position of the moving object when the moving object departs from its initial predetermined position. The invention can be used to track the movements of a space launcher close to the launching pad after take-off has occurred.</p> |
