(Abstract) GOES R ERA HIGH RESOLUTION DATA DISTRIBUTION

The presentation gives an overview of issues NOAA is facing in globally distributing the high resolution, very high rate data from the GOES R imager and sounder. Processed data rates of 24-80Mbps are possible to be made available. Today's global broadcast data rate is 2.1 Mbps. NOAA is concerned about the potentially high cost of distributing all data. NOAA wants to find the right balance of distributing needed GOES R information and being cost effective. NOAA is working to determine how and how much data to distribute, given the high cost. NOAA is exploring ways to reduce these costs. GOES satellite distribution as well as commercial communications satellite and dedicated land lines are being studied for real time distribution. NOAA is asking the nations of the Americas for information on their data needs in the GOES R era starting in year 2012. NOAA is considering a range of data rates as a broadcast possibility. No decisions have yet been made, for trade-off studies are still underway. NOAA plans to distribute e GOES R era data needed to support nations' weather and aviation services forecasts.

Roger Heymann is a registered Professional Engineer and a senior engineer in the Advanced Systems Planning and Requirements Division within the Office of Systems Development at NESDIS. He has been working on the GOES R planning since its inception. His work early in the GOES R planning was investigation of technology availability and concept designs for the imager and sounder instruments. He then started communications engineering studies to explore the impact on spacecraft design and cost, Radio Frequency availability, and communications concept designs for the high resolution data distribution. He has also investigated alternate distribution methods such as dedicated land lines and done studies comparing costs among different high data rate distribution methods. he has also co–led the efforts with NTIA to get for GOES R additional RF allocations. He has also been working to identify a validated list of nations needing GOES R data, and options for getting data to them.
