1.1 Basic Information
How does it work?
The Emerging Lifesaving Technologies ELT406GPS is a self-contained Emergency Locator
Transmitter that combines the new standard digital 406.037 MHz radio distress beacon with GPS
generated latitude/longitude location data. The signal is received by the Cospas/Sarsat satellite-
based search and rescue (SAR) system. In flight, the GPS unit automatically updates your
present position every 15 seconds. Upon activation, a 5 watt signal bursts every 50 ± 2.5 seconds
to the Global Satellite System. Your location within 25 meters* will then be transmitted to search
and rescue personnel. * Note Currently the Cospas Sarsat system only will receive Lat/Long in 4
sec increments. This represents about 300 feet on the equator.
Who’s in Control?
The International Cospas-Sarsat Program provides accurate, timely, and reliable distress alert
and location data to help search and rescue authorities assist persons in distress.
COSPAS (

) is an acronym for the Russian words "Cosmicheskaya Sistema Poiska
Avariynyh Sudov" (

), which translates to
"Space System for the Search of Vessels in Distress".
SARSAT is an acronym for Search And Rescue Satellite-Aided Tracking. The SARSAT system
was developed in a joint effort by the United States, Canada, and France. In the United States,
the SARSAT system is under the authority of the National Oceanic and Atmospheric
Administration (NOAA) which is a part of the U.S. Department of Commerce.

This manual provides “ acceptable data” to support installation into certified
aircraft. This installation requires that a certified person installs and completes the required
paperwork. For US registered aircraft that may require a (FAA Form 337). See section 4 of this
manual for a more detailed explanation of required documentation.
For Canadian registered aircraft the requirements of Canadian Aviation Regulations Part V, CAR
551.104 applies. Each country has their own requirements and you should contact the local
authority for specific details in returning the aircraft to service.
ELT406GPS has met or exceeded the minimum performance standards required for TSO
approval. A TSO (Technical Standard Order) provides minimum standards of operation and
safety for any given item. It is the responsibility of the installer of this equipment to ensure that
the aircraft installation meets both the local governing authority and the airframe manufacturers’
instructions.
