Specifications• Detects total lightning: in-cloud, cloud-to-

cloud, and cloud-to-ground• 70-90% flash detection day and night• Near uniform spatial resolution• Aids in forecasting severe storms and tornado

activity, and convective weather impacts on aviation safety and efficiency

• Currently no ocean coverage, and limited land coverage in dead zones

GOES Rebroadcast and Unique Payload Services

• GRB – GOES Rebroadcast (GRB)– GRB will contain the Level 1b data from each of the GOES-R Series instruments and is the

GOES-R Series version of today’s GOES Variable format (GVAR).• Information Network (HRIT/EMWIN)

– New high data rate (400 Kbps) – Combination of today’s LRIT (Low Rate Information Transmission) and EMWIN services; – Delivers selected imagery, charts, other environmental data products, and text messages

(NWS Watches and Warnings) to hemispheric users.• Data Collection System (DCS)

– GOES-R spacecraft relay data transmissions for nearly 30,000 in-situ environmental data platforms from across the hemisphere.

– GOES-R will support 300 bps, 1200 bps, and CDMA platforms.• SARSAT

– All GOES-R satellites support the Search and Rescue Satellite Aided Tracking (SARSAT) service by relaying distress signals from in-situ Emergency Position Indicating Radio Beacons (EPIRBs) and other transmitting devices.

GOES Rebroadcast (GRB) Data Transition

• Full set of level 1b products, including data from all ABI channels and the other GOES-R instruments (GLM, MAG, SEISS, SUVI, EXIS).

• GOES users must acquire new hardware, or upgrade their existing GVAR systems in order to receive GOES-R data.

• Existing GVAR systems will need new receiver antenna hardware, as well as new signal demodulation hardware and computer hardware so that they are able to handle the large amount of GOES-R data.

• CLASS will provide permanent archive for GOES-R data as part of its mission to be the single data repository for NOAA.

GOES-R Rebroadcast Services: Satya Kalluri– Tue, April 5, 2:30 pm12

GOES-R Changes Since 2008 DRO

• No eGVAR (Emulated GOES Variable Data)– Program will work with users to transition directly to GRB

• GOES-R L band frequency shift– Presidential Broadband Initiative
