Search And Rescue Satellite Aided Tracking SystemHow much is your life worth?
Consider getting a 406 MHz ELT for your aircraft

Beacon Segment until 2009Beacon Segment until 2009
• Two types: 121.5/243 MHz and 406 MHz
• Three applications:
- Emergency Position Indication Radio Beacons (EPIRB) for Maritime Uses
- Emergency Locator Transmitters (ELT) for Aviation Uses
- Personal Locator Beacons (PLB) for Remote Area Recreational users, aviators.

121.5 MHz Termination Date
• 1 Feb 2009 – Receivers on space craft will be shut off
• 121.5 MHz ELTs will no longer be picked up by the satellite systems
5
121.5 MHz Beacons121.5 MHz Beacons• Older technologyOlder technology
• Not designed for satellite processing (no store & forward capability)
• Analog signal only = no identification code
• Does not have global coverage!
• Low power ( < 1 watt)
• Less rigid standards
• Poor location accuracy = Usually no better than 12 miles = 450 SQUARE MILE SEARCH AREA
• USMCC handles 250-400 ‘hits’ per day. 99.9% are false!!
- Only 1 in 8 alerts come from beacons. The rest are ATM machines, pizza ovens, and even stadium scoreboards!
- High false alert rate makes first-alert launch unfeasible…

406 MHz Beacons406 MHz Beacons• New technologyNew technology
• Designed for satellite processing
• Digital signal w/ unique identification code
• Improved location accuracy
• Global coverage!
• Increased power ( 5 watt)
• Integral 121.5 MHz homing signal (low power)
• 5+ year lithium battery
• Mandatory registration (no cost)
• With registration information, improved location accuracy, and quicker detection times, beacon alerts can be responded to faster by search and rescue units

Personal Locator BeaconsPersonal Locator Beacons• Not a substitute for an ELT
but authorized as additional equipment
• Designed for outdoor Enthusiasts– Aviators, hikers, hunters,
climbers, boaters, …– Manual activation only– Automatically notify Federal
rescue forces
Update on US carriage requirements
• DOI, NTSB, USAF, NOAA, USCG have all asked FAA to disallow 121.5 MHz ELTS as satisfying carriage requirement
• FCC introducing rulemaking to disallow any new 121.5 beacons
• FAA conducting Cost Benefit analysis associated with retrofit in GA aircraft– Results due out end of July 2008
Update on International carriage requirements
• Canada– Mandated carriage of a 406 ELT or equivalent on
all Canadian Aircraft and all aircraft coming into or transiting Canada by 1 Feb 2009 currently in approval process
• Mexico– Mandated carriage of 406 ELTs by 1 July 2008.
• Allowance for 121.5 MHz until 1 July 2009 or until the current battery needs to be replaced, which ever happens 1st
How will we find you after 1 Feb 2009
If you stay with an older 121.5 beacon?
