Distress beacon capable of transmitting a distress signal when it is activated, comprising a transmitter stage (22) connected to an antenna (25), characterized in that it also comprises a receiver stage (21) fixed to a distress frequency and connected to the said antenna (25), a diplexer (23) for connecting the antenna (25) to the transmitter stage (22) and to the receiver stage (21), and a detection module connected to the output from this receiver stage (21) capable of activating a signal in order to indicate an alarm when a distress signal is received by the receiver stage on this distress frequency.
Process for reception of a distress signal on a distress frequency by a receiver stage of a vehicle, and processing of this signal, characterized in that a distress beacon is used installed onboard this vehicle capable of transmitting a distress signal when it is activated, comprising a receiver stage (21) dedicated to reception of such a distress frequency and an associated detection module, the said process also comprising the following steps:
- continuous listening of this distress frequency using this receiver stage (21),
- the detection module detects the reception of a distress signal on this distress frequency,
- a discrete signal is activated when such a distress signal is received,
- signal an alarm to the vehicle crew members.
