Method of communication between an airborne platform and a ground station using the VDL mode 2 standard with switching on a second ground station in case of breakdown of the communication with the first station.

摘要

This communications device (CMU) on board an airborne platform (PAE) is compatible with the frequency management mechanism defined by the VDL mode 2 standard. It comprises: activation module for activating a receiver module (VDR2) to scan an alternative frequency (FQ2) taken from a pair contained in a list (LST) of pairs received by a bidirectional module (VDR3) in communication with a ground station on another frequency; detector module for detecting at least one criterion representative of a break in communication with said ground station; and configuration module for configuring a bidirectional module (VDR3) for communicating on the alternative frequency (FQ2) with a target ground station (VGS2) heard by the receiver module.
