5 Why MEOSAR? Current System Performance LEOSAR GEOSAR + Can detect low powered beacons + Polar coverage - Wait time (minutes to hours dependent on location and terrain) - SARP on-board processing: structure of beacon message, coding methods are fixed - LEOSAR satellites are aging + Near-real-time detection - Limited coverage beyond 70ºN and 70ºS - Fixed geometry: line-of-sight beacon-to-satellite blockages - No Doppler location Current System No real time detection and independent location Limited options for possible evolution of 406 MHz beacon signal and technology System evolution to meet new requirements is slow 5

6 Why MEOSAR? Current LEOSAR payload life cycle

7 MEOSAR snapshot New American GPS, Russian GLONASS and European Galileo navigation satellites to embark 406 MHz repeater instruments on future medium Earth altitude orbiting (MEO) satellite constellations Constellations will be fully compatible Compatible with current gen beacons (not dependent on availability of second generation beacons) Operational alerts will be available in the mid-2016 time frame

8 MEOSAR Principles of Operation GALILEO Constellation GPS III Constellation GLONASS Constellation MEOLUT GALILEO GROUND SEGMENT RESCUE COORDINATI ON CENTER MISSION CONTROL CENTER RETURN LINK SERVICE

9 MEOSAR Single burst detection/location Fast Positioning by Triangulation

10 Why MEOSAR? Expected Performance Global coverage with real-time alerting and location data - single burst detection and location Accurate independent location capability 5 km or better, 95% of the time, without reliance on a navigation receiver Higher location accuracy with internal navigation receiver High level of satellite redundancy and availability No Doppler mirror image location generated Resilience to beacon-to-satellite link obstructions (i.e., satellite motion alleviates line-of-sight beacon-to-satellite blockages)

11 MEOSAR: Better Coverage MEO sat at 20,000 km LEO sat at 1,000 km

13 Actual pos: N E MEO pos: N E LEO res: N E Norway 15 August 2015 LEOSAR resolved position was approx. 1.5km from the crash site MEOSAR confirmed position was approx. 100m from the crash site 13

14 MEOSAR Space Segment Status (May 2016) 10 L-band Galileo satellites currently available (+2 launched 24 May, under test) New EC plans webpage to launch - Status 2 additional of L-band Cospas-Sarsat Galileo satellites by the end of 2016 MEOSAR Payload Instruments at 1 operational Glonass L-band satellite (another on orbit, TBD) 19 GPS II satellites carrying DASS repeaters with an S-band downlink DASS S-band constellation is not planned to be declared as operational, but its data may be used operationally the first L-band GPS satellite launch scheduled for 2023

15 MEOSAR development Reference Documents C/S R.012 Cospas-Sarsat 406 MHz MEOSAR Implementation Plan C/S R.018 Cospas-Sarsat Demonstration and Evaluation Plan for the 406 MHz MEOSAR System Proof of Concept Demonstration and Evaluation (D&E) Phase Early Operational Capability (EOC) Phase Pre-Initial Operational Capability (Pre-IOC) Section of C/S R.018 Initial Operational Capability (IOC) Full Operational Capability (FOC) 15

16 MEOSAR development MEOSAR D&E D&E Phase I and II, comprised of 8 technical tests and 7 operational tests - completed D&E Phase III entrance criteria for available L-band satellites met by June 2016 Phase III is anticipated to begin late summer or fall of 2016

17 MEOSAR Development Early Operational Phase (EOC) In December 2015, the Cospas- Sarsat Council (Can/Fra/Rus/USA), reviewed the EOC entrance criteria, agreed that they were met, and decided to begin MEOSAR EOC transition.

18 MEOSAR Development Early Operational Phase (EOC) The EOC period will: be initiated before the MEOSAR D&E Phase is completed and will allow early operational use of MEOSAR alert data allow the nascent MEOSAR system to augment the performance of the LEO/GEO system and allow SAR services to familiarize themselves with the MEOSAR system before entry into IOC

24 Second Gen Beacons Minimum Requirements Independent location accuracy First burst transmission within 3 seconds of activation Increased performance in first 30 seconds (Intelligent xmit) Alert Cancellation function Verification of Beacon Registration Homing and On-Scene Locating Objective Requirements Better resolution of encoded location 30 meters, 95% of the time within 5 minutes of activation 3-D location Return Link Service (RLS) Additional data encoded in beacon message In-flight ELT activation based on detection of emergency 24

25 SGB signal and homing Wideband (spread spectrum) signal - transmission of each burst is spread over the to MHz band, on an intelligent schedule - incompatible with most current homing equipment IMO and ICAO require an auxiliary homing signal (121.5 MHz) Homing signal characteristics under development Implementation will require C/S ground segment upgrades 25

27 In Conclusion The MEOSAR ground segment implemented by Argentina, Australia, Chile and South Africa will provide improved Cospas- Sarsat Antarctic coverage, with better timeliness of alert data MEOSAR should be an excellent resource for Antarctic SAR Early operational MEOSAR alerts will be available in mid-2016 RCCs should prepare to use this new data source by: Working closely with their supporting MCC Familiarizing operators with the new RCC Handbook
