  1. The Changing Face of Direct Readout “Oh Brave New World that has such people in it!” - Shakespeare (“The Tempest”) International EOS/NPP Direct Readout Meeting 3-6 October 2005 Richard Isaacman Vice President, SeaSpace Corp.

  2. From the GOES-R Mission Statement: The goals of the Geostationary Operational Environmental Satellites (GOES) program are to procure spacecraft, instruments, launch services, and a ground segment necessary to maintain an uninterrupted flow of environmental satellite data to users.

  3. Who Are the Historical DRO Users? • GOES GVAR Users • Very numerous (thousands) • Very low cost ground stations • Primary interest: weather data; operational • HRPT Users • Smaller in number but still very numerous (1-2 thousand?) • More expensive and elaborate ground stations (LEO) • Primary interest: both research and weather applications • X-Band Users (Mostly Aqua/Terra) • Small number (< 150) but influential • Complex and relatively expensive ground stations • Primary interest: research but seeing increasing operational use

  4. So What’s Happening Here? • Every mission is seeing both operational and research use, regardless of its original design concept. • …and NPP will embody this dual function by design • This dual role creates user communities that were not originally envisioned. This creates: • … demand for unanticipated data products • … new requirements for data archives and dissemination • … a de facto multi-mission role for every ground station NPP/NPOESS is the first DRO mission to acknowledge both of these issues in its mission concept.

  5. In Other Words… Operational to Research Multi-Mission Mixed Research and Operational Research to Operational EOS GOES, POES NPP/NPOESS GOES-R

  6. Good News/Bad News for Gov’t and Suppliers • Good News • More data goodness • Improved access to historical data • E.g., DAACs, Data Pools, NOAA CLASS • Access to higher-level products • …all of which act to increase the user base • Bad News • Need lots more computing power and storage • Larger and more complex data capture infrastructure • …in other words, cost (tends to decrease the user base)

  7. A Digression About Cost The small-to-medium size end-user market has historically been very price sensitive. Take LEO Direct Readout as an example: The number of users proliferates significantly as cost drops (N ~ 1/cost2 or faster) and technology matures. Anecdotally, there is a “takeoff point” below ~$100K where the user base gets very broad.

  8. The Result for Government and Industry:Shared Interest in an Expanded User Base

  9. Users Government Industry A 3-Way Partnership is Critical to Success THIS WON’T WORK Government Industry Users BUT THIS WILL

  10. Some Practical Steps Towards Creating a “User-Centric” DRO Ground Segment • Release processing software in a modular (rather than layered) fashion to allow system integrators to offer users a menu of options. • “It is important that agencies make pre-processing packages available to the greatest extent possible, whether they are developed in-house or in the research or commercial communities.”(CEOS Ad Hoc Team on Data Utilization, 11/2003) • Early release of libraries will aid transition and improve vendor support to customers • Use self-documenting file formats with OS-independent libraries. • HDF, netCDF, whatever • HRIT becoming a de facto standard; consider hopping on that bandwagon

  11. More Practical Steps • Processing software should be integrable into existing COTS structures. • Consider backwards compatibility • Real-time users who want L2+ products will still run vendor or own software packages • KISS! • Ground station architects (software and hardware) must coordinate more closely with network technologists • E.g., National Lambda Rail (NLR) in U.S. • Improve usability of existing large archives • Biggest areas of improvement: user interfaces, response time

  12. Some Final Inspirational Thoughts • The DRO user community is now highly multi-mission and interdisciplinary, and every new mission accelerates this trend. • Data acquisition and product processing requirements should not be cost-prohibitive for the user/customer. • Facilitating greater availability of data products will increase the size of the user base, thus fulfilling the IPO’s mission and benefiting both end users and suppliers. ← “The Inspiration of St. Matthew” (Caravaggio, 1602)
