ARTEX ELT/NAV INTERFACE UNIT

The Artex "ELT to NAV Interface" is designed to be connected between the aircraft's Flight Management Computer (FMC) or GPS receiver and the Artex 406 MHz series of ELT's. Its function is to receive continuous position updates from the aircraft's navigation system and translate it to the proper format for use by the ELT. Upon activation, the ELT transmits digitally the Latitude and Longitude of the aircraft to the COSPAS/SARSAT satellite system. Knowledge of the position information allows SAR forces to launch an immediate mission to the last known position of the aircraft.
