A system includes at least one reception unit installed in an aircraft and configured for tracking satellites of the satellite navigation system of the GNSS type. The system includes a generation unit for generating an expected number corresponding to the number of satellites that the reception unit is expected to track, a detection unit including a comparison part for comparing the expected number with a tracked number corresponding to the number of satellites that the reception unit is actually tracking and a decision part for detecting a jamming, as a function of the result of the comparison made by the comparison part and transmitting detection data in the event of detection, and a transmission unit configured to transmit jamming detection data to at least one user device, the system making it possible to detect a jamming of a GNSS system in an automatic and reliable manner.

A method and device for monitoring radioaltimetric heights of an aircraft, the device including an auxiliary height generation device that generates an auxiliary reliability height of an aircraft. The device also includes a determination device that determines with the aid of this auxiliary height, an error in incoherent data which are received from two radioaltimeters. To this end, the most reliable reading from the radioaltimeters is determined and sent to a user device.
