Fixed receiver of 406 MHz distress signals

The antenna, fixed receiver for distress signals emitted by 406 MHz beacons, is a device intended for communities or organizations that wish to ensure the safety of outdoor activity practitioners in their territory

The transmitter-receiver is in the form of an antenna connected to a box containing electronic radiocommunication components for detection and transmission. The device allows for the radio-electric detection of distress signals emitted by emergency location beacons that emit on the international distress frequency of 406 MHz.

The 406 MHz beacon receiver is installed on a high point, thus allowing coverage of a given geographical area. To cover an entire mountain range, several receivers must be strategically placed throughout the territory.

A single receiver covers a minimum radius of 50 kilometers. A topographic study of the area to be secured must still be carried out to optimize the placement of receivers.

This device meets the need and obligation of communities and organizations to secure the practitioners of sports and outdoor leisure activities in dangerous areas, with little or no equipment, under their territorial responsibility. This equipment compensates for the failures of telephone coverage that everyone has noticed. Vacation spots often have areas devoid of any telephone coverage or with random coverage that frequently changes.

The device allows users to communicate the geographic perimeter in which they can move with maximum safety.

The antenna, fixed receiver for distress signals emitted by 406 MHz beacons, is a valuable tool for ensuring the safety of outdoor activity practitioners in dangerous areas. By detecting distress signals and transmitting them to emergency services, the device can help to save lives.

A solution for communities to help reduce the number of serious accidents in mountain ranges, thanks to a fixed receiver for distress signals emitted by 406 MHz emergency beacons

The receiver-transmitter transmits information on the identification and precise location of a person who has reported their distress status via an emergency locator beacon.

The antenna is permanently in detection mode, listening to all signals emitted on the international distress frequency of 406 MHz, over a defined area. The receiver scans the entire 406 MHz band in less than 0.5 seconds.

When a distress signal is detected by the receiver, it transmits the alert. The message is received in less than one minute on a dedicated terminal, and then decoded to display the exact geographical position of the beacon on a user-friendly interface.

All information is systematically transmitted by email and telephone to the RCC (Rescue Coordination Centre), an organization under the authority of the French Air Force.

Alerts concerning identified beacons may be subject to specific treatment.

• The receiver scans the entire 406 MHz band in 0.5 seconds
• The interface displays the beacon's unique identification number, the reporting country, the emission frequency, and the geographical location in less than one minute
• Can decode up to 5 beacons simultaneously
• The interface is easy to use with an integrated map
• The system generates an alarm
