DETECTION OF A DISTURBANCE IN A MESSAGE FOR DIFFERENTIAL CORRECTION OF POSITIONING MEASUREMENT OF A SATELLITE GEO-POSITIONING DEVICE

摘要

The invention relates to a method and a disturbance detection device of a positioning measurement correction message from a satellite location-based device suitable for receiving a composite radio signal having a plurality of signals each transmitted by a satellite view the geolocation device, and a message (TM) differential correction positioning measurement transmitted from a satellite global positioning accuracy augmentation system. The device (20) of the invention includes calculation modules (32), for each of the satellites in view of at least one metric differential correction consistency depending on a differential correction of position measurement (C _AS) retrieved from the message (TM) received differential correction. The device (20) also comprises a detection module (34) Disruption correction message, when the number of satellites for which the metric differential correction consistency is above a predetermined threshold exceeds a predetermined number of satellites (N ₀ ), strictly greater than one.
