3. 12/23/20153 What is GOES VARiable (GVAR) - Overview GVAR primarily used to transmit Imager/Sounder data from GOES Satellites Also includes: telemetry, calibration data, text msgs, spacecraft navigation data, and auxiliary products. GOES I-P (8-15): –1685.7 MHz –2.11 Mbps –BPSK Modulation –L-Band http://www.osdpd.noaa.gov/ml/info/index.html#GOES http://www.oso.noaa.gov/goes/index.htm

4. 12/23/20154 Changes for GOES-14 GVAR Overview GOES-14 & GOES-P Imagers have an 8th IR detector –Starting with GOES-14, all IR channels at 4km resolution at nadir Imager factory coefficients were replicated to Block 11 beginning with GOES-12 (GVAR Version 2) GVAR format was modified to accommodate the additional detector data – added to Block 0 while removing imager factory coefficients (GVAR Version 3) However, plan is to replicate Instrument Nadir and Detector Offsets to currently unused space at the end of Block 0 in addition to the Block 11 position White Paper “Copying the Instrument Nadir and Detector Offsets from Block 11 to Block 0 for GOES O and Beyond” published at conference http://www.osd.noaa.gov/gvar/gvardownload.htm http://www.osd.noaa.gov/gvar/gvardownload.htm

5. 12/23/20155 Changes to GVAR Summary GOES- 8 through 11: –Instrument Factory Coefficients in Block 0 (GVAR Version 1) GOES- 12 and 13: –Instrument Factory Coefficients both in Block 0 and Block 11 (GVAR Version 2) GOES-14 and 15 (GVAR Version 3) : –The data for the 8 th detector have been added to block 0 –Instrument Factory Coefficients are located in Block 11 –Instrument Nadir and Detector Offsets located in Block 11 but will also be located in Block 0 Detector Offsets to be located in block 0, words 7933 to 8028 Instrument Nadir to be located in block 0, words 8033 to 8038 Requirement: have guaranteed delivery of Detector Offsets + Instrument Nadir in the start of a frame to ensure proper INR operations in the RPM system.

7. 12/23/20157 What is GOES Data Collection Service (DCS) - Overview GOES data service for collection of environmental data in real-time from > 30,000 remote data collection platforms located across the GOES Footprint GOES 11-14 –Uplink at 401.7-402.1 MHz at 100/300/1200 BPS –Downlink at 1694.5 MHz Frequency Share/Time Share System –Approximately 200 Channels –Normal transmissions hourly for 5 to 10 seconds Data available from NOAA or through direct broadcast –GOES Direct Broadcast (large antenna, by channel) –DOMSAT (commercial satellite, small antenna, one stream) –Internet connection –LRIT

8. 12/23/20158 What is GOES Data Collection Service (DCS) - Overview Critical infrastructure for real-time data collection Many Emergency warning systems in the U.S. and other countries rely on GOES DCS Examples of GOES DCS User Community: –National Weather Service/National Ocean Service –USGS –U.S. Forest Service –International Hydrometeorological Offices Examples of Applications of DCS Data –Tsunamis and other sea level information –Floods, earthquakes, volcanoes –Fire (fuel temperatures, wind directions and speed) –Meteorological observations

9. 12/23/20159 GOES DCS Current System Improvements New ground system (DADDS) in operation New transmitters to cut channels in half, double capacity coming soon Finishing conversion to faster transmitters, eliminating slower (100 bps) transmitters Future implementation of available 2-way communication capability Allowing more frequent observations (1 hour instead of 3 or 4 hour repeat cycle) http://www.noaasis.noaa.gov/DCS/
