MEO Orbit Basics
MEO Walker Constellation 8 satellites in 8 planes
MEO Equatorial and Polar Constellation 4 satellites in equatorial orbit, 4 in polar orbit
4 MEO Satellites in Equatorial Orbit Achieve Global Coverage +60o
Medium Earth Orbits (MEOs) Potential Benefits • Can achieve near real-time global coverage with relatively small number of same type of satellites • 1/3 the orbit of GEOs – potential to reduce instrument apertures (ex: passive microwave) • Robust constellation – able to reposition satellites to reduce impact of on-orbit failures Challenges • New science – no constant sun angles of polar sun-synch nor constant viewing angles of GEOs • New instrument configurations
GOES R Constellation Architecture Studies Preliminary Conclusions • MEOs probably not viable as GOES R 2012 candidate • However, great potential for later augmentation to GOES R (P3I) or as part of future integrated satellite architecture

Future MEO Insertion/ Transition Opportunities • NPOESS – 2009 to 2020+ • GOES R-Series – 2012 to 2025+ • MEOs • System capability insertion to meet Pre-Planned Product Improvement requirements ~2016 • Transition to future integrated satellite constellation ~2020+
Challenges/Future Opportunities • Challenges • Determine optimum integrated satellite constellation architectures to balance trade-off between operational capability and affordability • Understand science to accommodate new orbits (MEOs) • Develop new instrument designs/architectures – new orbits, new technology applications at different orbits, multi-mission instruments • Opportunities • Integrated satellite architectures, providing • Improved linkages to NOAA/National/International Integrated Observing Systems • Better support to operational users
