NOAA GOES DCS Data ServicesThe OSPO provides GOES DCS ground system support at twofacilities; the prime system is at the Wallops CDAS while thebackup is at the NSOF. Wallops Operations monitors andcontrols both systems. The DCS supports the followingdissemination services:• DOMSAT

– CONUS rebroadcast from Wallops or NSOF • NWSTG

– WMO Header service from Wallops or NSOF DADDS• LRGS

– File sharing service from/with Wallops, EDDN & NSOF DAMS-NT• LRIT

– GOES 13-15 link, DCS data from NSOF DADDS or Wallops LRGS• HRIT

– GOES R Series link, DCS data from Wallops or NSOF DADDS

NOAA DCS DOMSAT• Wallops CDAS, VA is Prime and NSOF Suitland, MD is Backup• Conus Coverage• Annual cost for Wallops and NSOF backup site ≈ $15k

– Funded by the OSPO

NOAA LRGS Support

• The Wallops CDAS monitors and maintains NOAA LRGS Network

• The LRGSs can be monitored through “LRGS Summary Status” web page,available through the DADDS webservers 1-4:

– https://dcsX.noaa.gov ►”LRGS Status” ► https://dcsX.noaa.gov/lrgs/LrgsSummaryStatus.html

• The Emergency Data Distribution Network’s (EDDN) 3 LRGSs can also bemonitored through the LRGS Summary Status:- https://eddn.usgs.gov/lrgs/LrgsSummaryStatus.html

• CDADATA and CDABACKUP LRGSs provide GOES LRIT backup source.

GOES Spacecraft Constellation

• GOES-13: Prime East S/C @ 75° W Longitude• GOES-15: Prime West S/C @ 135° W Longitude• GOES-14: Storage @ 105° W Longitude • GOES-16: Scheduled to replace G13 Nov 2017• GOES-S: Scheduled for launch Spring 2018

GOES 16• NOAA’s newest geostationary satellite will be positioned as GOES-East this fall, November

2017, as announced in a NOAA press release, dated 25 May, 2017(http://www.noaa.gov/media-release/noaa-s-newest-geostationary-satellite-will-be-positioned-as-goes-east-fall).

• Reminder: The GOES R satellite series frequency plan is different from the plan currentlyin use by the GOES 13, 14 and 15 satellites. GOES DRGSs currently support the GOESEast (GOES 13) DCS downlink in the frequency range of 1694.30 to 1694.70 MHz. TheGOES R series satellites will use 1679.70 to 1680.10 MHz to support the DCS downlink.GOES DCS users will need to modify their DRGSs to accommodate this change indownlink frequency, to be able to support GOES 16 this November.

• Note that the GOES 16 frequency plan changes do NOT affect the Data Collection Platform(DCP) UHF-Band uplink transmissions, only the L-Band downlink to NOAA and theDRGSs. There will also be NO frequency changes in the DCS DOMSAT Ku-Band service.

• http://www.goes-r.gov

DCPR Changes for GOES-R

• On the GOES-N/O/P satellites the DCPR downlink band is 1694.3 – 1694.7 MHz– The uplink Pilot at 401.85 MHz is translated to 1694.45 MHz in

the existing downlink

• For the GOES-R series satellites the DCPR downlink band will be 1679.7 – 1680.1 MHz– The uplink Pilot at 401.85 MHz will be translated to 1679.85

MHz in the new downlink

• No uplink frequencies will change from the GOES-N to GOES-R satellites – only the downlinks
