Yes, they appear to be moving towards the Loral Cyberstar-Skybridge architecture. Still have a different (much higher) frequency, as I recall. The advantage is they have lots of it to themselves. The disadvantage is that it still has lots of rain etc. interference problems, and is on the bleeding edge, technology wise, to implement effectively. As I recall. Cyberstar-Shybridge is on the other hand using more docile and cheaper frequencies. But also more crowded ones. As I recall they have to figure out how to turn off their sats when they pass through the spot beams of GEOs overhead using the same frequencies. Anyone have any further thoughts? Oh, and doesn't it look like our boys will be first to market by a couple of years? Doug

"Even though the Celestri-Teledesic combination eliminates one competitor, this may leave the Cyberstar-Skybridge system in a precarious position. As a pure LEO system, Teledesic promised to be a megaflop, but with a GEO component and a deep reduction in the number of LEO satellites, the overall system will become quite attractive, IMHO" Bernard: I agree completely, except for the precarious position part. They will be in the catbird's seat--C* begins service this fall. Dedicated Ka-band transponders on Telstar in phase 3. Their own super high power LS-2020 sats in 2003, joining Skybridge's 64 LEOs launched in 2001. Bring on the competition. By the way, each C* sat will have 64 spot beams with 85Mbps capacity, or 5,440 Mbps. As a comparison, Telstar 5 has a total capacity of 864 Mbps. Who said something about low capacity?
