Abstract: A module making it possible to detect a disturbance signal during initial receiving by a receiver of navigation information, the receiver including a plurality of elementary antennas able to receive, in a plurality of arrival directions, electromagnetic signals including navigation information, a forming unit able to form a resultant signal from the electromagnetic signals and a processing unit able to process the resultant signal, the detection module being integrated into the forming unit and able to receive the electromagnetic signals coming from each of the elementary antennas, analyze the signals and detect a disturbance signal when the receiver is started cold in case of detection of a favored arrival direction of some of the electromagnetic signals.

Abstract: The invention relates to a disruption detection method and device for a positioning measurement correction message of a satellite geolocation device, able to receive a composite radio signal including a plurality of signals each emitted by a satellite in view of the geolocation device, and a positioning measurement differential correction message (MC) emitted by a satellite geolocation precision augmentation system. The device (20) according to the invention includes modules (32) computing, for each of the satellites in view, at least one differential correction coherence metric depending on a positioning measurement differential correction (CAS) extracted from the received differential correction message (MC). The device (20) also includes a module (34) detecting a disruption of the correction message when the number of satellites for which the differential correction coherence metric is above a predetermined threshold exceeds a predetermined number of satellites (N0), strictly greater than one.
