An interesting site; tons of links & info on constellations in general,
Teledesic & Iridium in particular.
His SaVi projections of planned footprint coverage of both Iridium & Teledesic
are both highly interesting.
Lloyd Wood, the guy who maintains the site, is a PhD student who
obviously thinks _a lot_ about these things. The stuff on IP over LEO vs.GEO
is quite good, and he puts himself clearly in the anti-ATM camp with:
