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 NGOES N - - Dedicated transponder- Full digital data stream- Improved product suite (128 kbps)- Ground system will require upgrades

WEFAX (cont)WEFAX (cont)

GOES-R Era

- Improved data rates (256 kbps)

- Modulation change from BPSK to Off-set QPSK (OQPSK)

- Downlink frequency change from 1693.4 MHz to 3 MHz higher (proposed)

GOES Variable GOES Variable (GVAR) (GVAR) GOES M GOES M - 6.7 micron resolution changes - 8km to 4km

- 12 micron channel replaced with 13.3 m channel

- New format / Blackbody calibration changes

GOES N - GOES N - minor changesminor changes

GOES RGOES 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 1690.725 MHz to 1692.7 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 1692.7 MHz or 3 MHz higher (proposed)

- Date rate increase (56 kbps)

- Ground system will require upgrades

Search and RescueSearch 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 250,000 406 MHz users currently

- Over 900,000 406 MHz users expected by launch of GOES-R

- 33 Countries formally part of Cospas-Sarsat

Search and RescueSearch 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 RescueSearch 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 406.0 – 406.1 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)
