[edit] Descriptions

English:

The radio beacons of localization of disasters (RLS) EPIRB emit on band 406 to 406,1 MHz and 121,500 MHz with an endurance of 100 H with +20°C and an endurance of 40 H with -40°C.

A radio beacon has a power ranging between 0,025 W and 0,35 W out of 121,500 MHz. The Amplitude modulation emitted on this frequency corresponds to a sweeping of more than 700 Hz between 300 Hz and 1 600 Hz. The emission on frequencies 121,500 MHz, (243,000 MHz military version), requires a radiogoniometric location by the teams of research on the ground.

a radio beacon has a power ranging between 3 W and 7 W on tape 406 to 406,1 digital MHz in transmission coded of the one 440 ms duration MMSI all the 50 s for indication and the répérage by Cospas-Sarsat satellite


Français :

Les radiobalises de localisation des sinistres (RLS) EPIRB émettent dans la bande 406 à 406,1 MHz et sur 121,500 MHz avec une autonomie de 100 H à +20°C et une autonomie de 40 H à -40°C.

Une radiobalise a une puissance comprise entre 25 mW et 350 mW sur 121,500 MHz. La Modulation d'amplitude émise sur cette fréquence correspond à un balayage de plus de 700 Hz entre 300 Hz et 1 600 Hz. L'émission sur les fréquences 121,500 MHz, (243,000 MHz version militaire), nécessite un repérage radiogoniométrique par les équipes de recherche au sol.

Une radiobalise a une puissance comprise entre 3 W et 7 W sur la bande 406 à 406,1 MHz en transmission digital codé du MMSI d'une durée de 440 ms tous les 50 s pour la signalisation et le répérage par satellite Cospas-Sarsat
