From the GEONETCast Americas Coordination Group and AmeriGEOSS GEONETCast Americas (GNC-A): Delivering Regional and National Data, Products and Observations Presented by: Paul Seymour, NOAA/NESDIS Ms. Irene Parker Meeting, Silver Spring; November 2, 2016
GEONETCast Americas What is GEONETCast? • GEONETCast is a distribution system for environmental satellite data and products using commercial TV satellites and low cost, off-the- shelf reception technology; • GEONETCast is a Foundational Task under the GEO Common Infrastructure – Previously: part of GEO Task – IN-04: GEOSS Communication Networks • GEONETCast Americas is a Foundational Task within AmeriGEOSS
GEONETCast Americas Mission and Objectives • GEONECast’s Mission: “Provide data distribution system within GEOSS by which environmental data and products will be transmitted to users through regional networks over communications satellites.” • Objective: “Provide global information as a basis for sound decision making in critical areas”. – “Focus on areas of the world where high speed land lines and/or internet are not available or in regions where terrestrial communication lines have been disrupted by disasters.” • WMO Region III/IV Satellite Data Requirements and Support GEOSS Societal Benefit Areas
GEONETCast Americas General Description • Regional component of the Global GEONETCast • Provided by the U.S./NOAA • Footprint covers • Most of North America Caribbean Region Central South America • Operational since Spring 2008
GEONETCast Americas Commercial Satellite Broadcast • 6.7 total (6.35 content) megabits per second data rate • Intelsat-21 (IS-21) geostationary satellite • Multiplexed C-band DVB-S transponder at 58 deg W • > 99.5% availability – in actual operations close to 100%
