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
•
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.
3
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
4
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…
5
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)
•
6
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
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
8
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.
9
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
10
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?
