    You can also use LEO com sat constellations like Iridium or Orbcom.
    
    Lack of geo coverage at the high latitudes is also why the Russians  
    have their Molynia com sats in highly elliptical orbits.  With three  
    in a constellation at least one is always hanging over the north pole.
