GOES Weather Facsimile (WEFAX) GOES M - Analog to Digital - Timeshare between analog and digital - Low Rate Information Transmission ( LRIT) CCSDS like protocol Multiple product transmission (64 kbps) Compatible with the Europeans and Japanese Ground system will require upgrades GOES N - - Dedicated transponder - Full digital data stream - Improved product suite (128 kbps) - Ground system will require upgrades

WEFAX (cont) GOES-R Era - Improved data rates (256 kbps) - Modulation change from BPSK to Off-set QPSK (OQPSK) - Downlink frequency change from MHz to 3 MHz higher (proposed)

GOES Variable (GVAR) GOES Variable (GVAR) GOES M micron resolution changes - 8km to 4km micron channel replaced with 13.3 m channel - New format / Blackbody calibration changes GOES N - minor changes GOES R - - New format - GOES Re-Broadcast data stream - Full imager and sounder data stream - Packetized data format - Downlink frequency TBD

Emergency Managers Weather Information Network ( EMWIN) GOES-M Era - Continue to share GOES transponder with WEFAX service - Test timeshare with LRIT service on non- operational GOES spacecraft GOES-N Era - Transmit on separate GOES transponder - Downlink frequency will change from MHz to MHz - Ground system will require upgrades - Data rate will be 9.6 kbps - Modulation changes from FSK to BPSK

EMWIN (Cont) EMWIN (Cont) GOES-R Era - Downlink frequency changes to MHz or 3 MHz higher (proposed) - Date rate increase (56 kbps) - Ground system will require upgrades

Search and Rescue Search and Rescue - NESDIS manages and operates the U.S. portion of the International Cospas-Sarsat Program - Cospas-Sarsat provides, free-of-charge, distress alert and location information to search and rescue authorities anywhere in the world for maritime, aviation and land users in distress. - Over 250, MHz users currently -Over 900, MHz users expected by launch of GOES-R -33 Countries formally part of Cospas-Sarsat

Search and Rescue Search and Rescue Local User Terminal Mission Control Center Rescue Coordination Center POES Satellites GOES Satellites Emergency Beacons

Search and Rescue Search and Rescue -Advantages of GOES: -Near real-time detection for 406 MHz emergency beacons - Near real-time location for 406 MHz beacons equipped with GPS -Advantages of POES: - Doppler location for existing 406 MHz beacons - Global coverage - Increased reliability (due to changing geometry)

Search and Rescue Search and Rescue Future Enhancements -Phase out of 121.5/243 MHz Satellite Processing - - increased number of 406 MHz beacon users through GOES -Expanded use of GOES – MHz band through the introduction of new channels in the band -Possible two-way capability on GOES-R that would allow a return link to the emergency beacon user (option being studied)
