-Welcome to SARSAT 101 Beacons Ground Stations (LUTs) Mission Control Centers (MCCs) Rescue Coordinations Centers (RCCs) 121.5 MHz Phaseout, Carriage Reqs, The Future The Bottom Line Overview

COSPAS =Cosmicheskaya Systyema Poiska Aariynyich Sudov Which loosely translates into: “The Space System for the Search of Vessels in Distress” SARSAT =Search And Rescue Satellite Aided Tracking What is Cospas-Sarsat??? In short, Cospas-Sarsat takes the “search” out of Search & Rescue
4
NOAA’s SARSAT Program protects life and property by providing accurate, timely, and reliable distress alert and location information to search and rescue authorities. The SARSAT Mission…

Emergency Beacons 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 Uses - NOW AVAILABLE!!!
7
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 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…

121.5/243 MHz Coverage “Holes”
9
243 MHz Beacons Similar to 121.5 MHz beacons Primarily used by the military Many existing 121.5 MHz also transmit on 243 MHz
10
406 MHz Beacons Newer technology Designed for satellite processing (store & forward) Global coverage Digital signal Increased power (5 watt) Unique Identification Rigid specifications More Accurate = 2 - 3 mile location accuracy. Even better with integral GPS units = 100 meter accuracy!
11
Beacons with Navigation (GPS) Input Improved location accuracy Instantaneous detection AND location! 121.5 MHz 406 MHz 406 MHz with GPS Search Time = 12+ hours Search Time = 2 - 3 hours Search Time = Minimal
13
2 Types of Satellites: Low Earth Orbiting Search And Rescue (LEOSAR) (8) Satellites in Orbit: -COSPAS 4, 9, 10 -SARSAT 4, 6, 7, 8, 9 Geostationary Orbiting Search And Rescue (GEOSAR) (4) Satellites in Orbit: -GOES 8 (West) -GOES 10 (East) -INSAT 3A -MSG Cospas-Sarsat Space Segment
14
121.5/243 MHz Beacon LEO Satellite LUT Detection of a 121.5/243 MHz beacon requires mutual visibility between beacon, satellite and ground station (LUT) 406 MHz Beacon LEO Satellite LUT 406 MHz beacon detections can be stored on board the satellite and re-broadcast later
16
LEOSAR Local User Terminals (LEOLUT) Track COSPAS and SARSAT satellites Recover beacon signals Perform error checking Perform Doppler processing Send alert to Mission Control Center Cospas-Sarsat Ground Stations

22
Mission Control Centers (MCC) Receive alerts from national LUTs and foreign MCCs. Validate, match and merge alerts to improve location accuracy and determine the correct destination. Query 406 MHz Registration Database and transmit registration info with distress alert. Transmit alerts to Rescue Coordination Centers (RCCs) and SAR Points of Contact (SPOC) and filter redundant data. All USMCC functions are handled automatically…no manual intervention. 24 x 7 x 365 operational center

International Organization Initially developed under interagency Memorandum of Agreement signed in 1979 International Cospas-Sarsat Programme Agreement signed on July 1, 1988 among the governments of Canada, France, the former U.S.S.R and the United States Association with Programme allows States to contribute towards the ground segment or participate in international Cospas-Sarsat meetings Goals of Cospas-Sarsat are to support SAR objectives of ICAO and IMO. Therefore, C-S maintains a close partnership with these U.N. agencies and the ITU

International Maritime Organization UN specialized agency responsible for improving maritime safety (Mandates use of emergency beacons) International Civil Aviation Organization UN specialized agency responsible for aviation matters and improving civil aviation safety (Mandates use of 406 MHz beacons) International Telecommunications Union UN specialized agency responsible for coordinating global telecommunications (406 MHz beacon specifications)

*** 121.5/243 MHz PHASE-OUT DECISION *** International Cospas-Sarsat Council (in conjuction with IMO/ICAO) announces the Termination of 121.5 MHz Satellite Alerting on 01 February 2009 at its 25 th General Session (October 2000)
39
*** 121.5/243 MHz PHASE-OUT DECISION *** So, what does this mean to you and that old 121.5 MHz EPIRB of yours???... Again, here are the reasons why this decision was made: Coverage – Global vs Local False Alerts Identification Accuracy Alerting
40
All vessels 300 gross tons or greater (SOLAS) Vessels engaged in transporting 6 or more persons *** In the U.S. all Commerical Fishing Vessels *** All vessels in Hawaiian waters operating beyond 1 nmi of shore shall carry a 406 MHz EPIRB or DSC-VHF Radio (State legislature passed law in May, 2003. Effective Jan 1 st, 2004) FCC/USCG 406 MHz Vessel Carriage Requirements …it becomes “illegal for use” on Jan 1 st, 2007!!! This is a new regulation under the recently issued FCC Title 47, Part 80 rules (August, 2003) Can no longer purchase a 121.5 MHz EPIRB as of Feb 1 st, 2003
41
The Future of Cospas-Sarsat… The Distress Alerting Satellite System 406 MHz “bent-pipe” repeaters on future GPS satellites Full compatibility with existing + future 406 MHz beacons Continued global detection and location: – Greater than current Cospas-Sarsat accuracy Alert data downlink will continue to be freely available internationally Possible two-way return link GPS Satellite

2002 COSPAS-SARSAT Rescues 1,545 persons rescued in 365 SAR events worldwide - 1341 maritime rescues in 239 SAR events - 83 aviation rescues in 47 SAR events - 121 land rescues in 79 SAR events 2002 U.S. SARSAT Rescues 171 persons rescued in 69 SAR events nationwide - 133 maritime rescues in 64 SAR events - 11 aviation rescues in 5 SAR events - 27 land rescues in 18 SAR events Since 1982 over 15,000 lives rescued via Cospas-Sarsat! Nearly 5,000 in U.S. AOR’s alone! The Bottom Line…
