The ARTEX ELT 1000 is a value-priced upgrade to standard 121.5 MHz transmitters, which are no longer monitored by the Cospas-Sarsat system. The 406 MHz transmitter produces a much more accurate position, typically 3 kilometers as compared with 15 to 20 kilometers for 121.5 MHz transmitters. When coupled to the aircraft navigation system via a navigation interface, the ELT 1000's accuracy improves to approximately 100 meters.
Because it is a single output ELT, the ELT 1000 utilizes the same RF output and only one coax cable to transmit a 406 MHz emergency signal to Cospas-Sarsat satellites and a local 121.5 homing signal. With its new built-in navigational interface that does not require plane power to operate, the cost of installation is greatly reduced.
The new 2-wire interface is compatible with older 121.5 MHz ELTs, so upgrading your ELT is simple and affordable.
