MEO Equatorial and Polar Constellation4 satellites in equatorial orbit, 4 in polar orbit

4 MEO Satellites in Equatorial OrbitAchieve Global Coverage +60o
10
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
Medium Earth Orbits (MEOs)
11
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+
21
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
