OneWeb Constellation Summary:

  • OneWeb Constellation operates in a LEO Polar Orbit
  • Satellites are arranged in 12 rings (Orbital planes) with 49 satellites in each plane.
  • The orbital planes are inclined to be near polar (87.9 Deg.)
  • The orbital planes are 1200 km above the Earth
  • Each satellite completes a full trip around the earth every 109 minutes.
