Search And Rescue Satellite Aided Tracking System

How much is your life worth?

Consider getting a 406 MHz ELT for your aircraft

beacon segment until 2009
Beacon 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
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
121 5 mhz beacons
121.5 MHz Beacons
  • Older 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 beacons
406 MHz Beacons
  • New 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
406mhz location accuracy search area reduced by a factor of 45 times
406MHz Location AccuracySearch Area Reduced By A Factor Of 45 Times

406.025 MHz Beacon

Location Accuracy = 2.0 nm

Search Area = 12.5 nm2

406 MHz Beacon w/ GPS

Location Accuracy = 0.21 nm

Search Area = 0.15 nm2

121.5 MHz Beacon

Location Accuracy = 12nm

Search Area = 452nm2

emergency locator transmitter
Emergency Locator Transmitter

ELTs are designed specifically for use aboard aircraft

All ELTs have automatic (G-force/Crush force) and manual activation modes

Automatically notify Federal rescue forces

Mandated carriage on most General Aviation

and Business Jets.

personal locator beacons
Personal 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
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
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
