purpose of briefing provide the latest status of goes services
Purpose of Briefing - Provide the latest status of GOES services
  • GOES VARiable (GVAR)
    • Low Rate Information Transmission (LRIT)
  • Direct Collection Services (DCS)
  • Emergency Managers Weather Information Network (EMWIN)
  • Search And Rescue Satellite Aided Tracking (SARSAT) System
  • http://www.osdpd.noaa.gov/ml/svcs/index.html
what is g oes var iable gvar overview
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

changes for goes 14 gvar overview
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
changes to gvar summary
Changes to GVARSummary
  • 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 8th 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.

what is goes data collection service dcs overview
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
what is goes data collection service dcs overview8
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
goes dcs current system improvements
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)

what is emergency managers weather information network emwin overview
What is Emergency Managers Weather Information Network (EMWIN) - Overview

EMWIN is a reliable, low cost, weather warning and data broadcast system providing free and rapid dissemination of warnings, forecasts, graphics and imagery in the Americas, the Caribbean and Pacific Rim that has been in operation for over 14 years

The Goal - to inform emergency managers and the public as quickly as possible of pending weather threats, increasing the likelihood of sparing lives and property

EMWIN is a National Weather Service Network disseminated via GOES and the Internet
