1 S A R S A T Search & Rescue Satellite-Aided Tracking

2

3 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

5 Rescues In 2001: 1,545 persons rescued in 365 SAR events - 1341 maritime rescues in 239 SAR events - 83 aviation rescues in 47 SAR events - 121 land rescues in 79 SAR events Since 1982 over 14,000 lives rescued via Cospas- Sarsat! Nearly 5,000 in U.S. AOR’s alone!

6 Rescues in 2001

7 Emergency Beacons Two types: 121.5/243 MHz and 406 MHz Three applications: - Emergency Position Indication Radio Beacons (EPIRB) - Emergency Locator Transmitters (ELT) - Personal Locator Beacons (PLB)

8 121.5 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 400-600 ‘hits’ per day. 99.5% are false!! Will Not Be Detected by Satellites After February 1, 2009!

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 Will Not Be Detected by Satellites After February 1, 2009!Will Not Be Detected by Satellites After February 1, 2009!

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 Input Improved accuracy Instantaneous detection 121.5 MHz 406 MHz 406 MHz with GPS

12 Space Segment Two types of satellites Low-Earth Orbiting Search and Rescue (LEOSAR) Geostationary Orbiting Search and Rescue (GEOSAR)

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, 10 -INSAT 2B -MSG (recently launched & undergoing testing) Space Segment

14 121.5/243 MHz Beacon Satellite LUT Detection of a 121.5/243 MHz beacon requires mutual visibility between beacon, satellite and ground station (LUT) 406 MHz Beacon Satellite LUT 406 MHz beacon detections can be stored on board the satellite and re-broadcast later

15 Local Mode (‘Bent Pipe’) Operations

16 Global Mode (‘Store & Forward’) Operations

17 Typical Satellite Footprint GEO Footprint LEO Footprint

18 Typical 121.5/243 MHz Coverage “Holes”

19 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

20 Maryland Puerto Rico Texas Alaska Hawaii United States LEOLUTs Guam California (Deployable LUT)

21 LEOSAR Local User Terminals (LEOLUT) – 41 Locations Worldwide

22 GEOSAR Local User Terminals (GEOLUT) Track GOES and INSAT satellites Recover beacon signals Perform error checking Send alert to Mission Control Center

23 GEOSAR Local User Terminals (GEOLUT) – 8 Locations

24 Receive alerts from national LUTs and foreign MCCs Validate, match and merge alerts to improve location accuracy and determine the correct destination Geographically sort and then transmit alerts to appropriate Rescue Coordination Centers (RCCs) and SAR Points of Contact (SPOC). Filter redundant data Perform System support and monitoring functions Mission Control Centers (MCCs)

37 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)

38 ICAO Convention Aircraft New aircraft that fall under the ICAO convention should carry 406 MHz ELTs by 2002 All aircraft that fall under the ICAO convention should carry 406 MHz ELTs by 2005 406 MHz Carriage Requirements IMO - SOLAS Class Vessels All vessels 300 gross tons or greater Vessels engaged in transporting 6 or more persons ***In the U.S. all Commerical Fishing Vessels***

39 Phase-Out of 121.5/243 MHz Satellite Alerting 121.5 MHz BEACON USAGE – International Termination of 121.5 MHz Satellite Alerting on 01 February 2009! – U.S. Termination of 121.5 MHz EPIRBs = 3 Phases Certification of new 121.5 EPIRBs cease immediately Sales and manufacture of 121.5 MHz EPIRBs cease on 01 February, 2003 Operation/Use of 121.5 MHz EPIRBs becomes illegal on 31 December, 2006 – 121.5 MHz ELTs will still be in use and required on general aviation aircraft…
