2 OUTLINE Program Mission Program Status Launch Planning GOES-R Series

3 GOES MISSION GOES satisfies National Weather Service (NWS) requirements for 24 hour observation of weather and Earth’s environment to support storm-scale weather forecasting by forecasters and numerical models To meet requirements, GOES continuously maintains operational satellites at two locations (75 degrees West and 135 degrees West), with and on-orbit spare ready in case of failure Data are provided to users routinely from the Imager every 15 minutes and from the Sounder every hour throughout the day from each satellite. More rapid repetition is used when needed for severe weather events. Operational SpacecraftOn-Orbit Storage

5 GOES On-Orbit Status GOES-8 continues to function as the GOES-East operational satellite –Functioning on several redundant systems –Depletes all fuel reserves by April 2003 –Has exceeded operational life by 3 + years GOES-9 removed from operational service in July 1998 –Being made available to the Japanese to provide emergency coverage, if necessary GOES-10 has functioned as the GOES-West operational satellite for the last 41/2 years –Difficult to quantify remaining mission life due to Solar Array anomaly GOES -11 and GOES –12 are in on-orbit storage mode, ready to replace either GOES-East or West –Transition plan being developed to move GOES-12 to GOES-East

6 GOES-N Series Development/Production Status GOES-N Series Spacecraft (Boeing Satellite Systems (BSS), Inc.) –Government provided instruments delivered to Spacecraft contractor and successfully integrated on GOES-N Spacecraft –GOES-N Spacecraft system level testing underway –GOES-N Series Spacecraft Support Ground System (SSGS) delivered to NOAA’s SOCC Successfully completed two command/TLM/Data End-to-End testing between Spacecraft and NOAA’s SOCC –GOES-N Spacecraft on schedule to support January 2004 launch readiness –The GOES-O Bus and Payload Modules Completed

7 GOES-N - Anechoic Chamber

8 GOES-N Series Instruments Status GOES-N Series Imagers and Sounders (ITT) –The GOES-N (S/N08) Imager and Sounder mechanically/electrically integrated onto the GOES-N bus –The GOES-O (S/N09) Imager and Sounder mechanically integrated on to the GOES-O bus –GOES-P (S/N10) Imager and Sounder are in temporary storage at ITT. –Preliminary integration of S/N 11 Imager and Sounder started, leading to the ship dates of June 14, 2003 for the Imager and July 31, 2003 for the Sounder.
