Jack,

My point is that if Worldphone (Inmarsat) has a substantial customer base at their prices and operational limitations, then I* should be a shoe-in. It sounds like the "M" service uses satellite spot beams thus they may not have full pole to pole earth coverage like I*. Aiming the antenna in the cover does take away from the mobility too, especially now that people are so accustomed to the convenience of cell technology. But I have no idea how many customers have purchased Inmarsat "M" service. I would bet that their sales are way off lately:-)

One interesting tale back when Inmarsat was strictly for marine use. Supposedly there were ranches in Mexico named to sound like ships so they could obtain Inmarsat service since it took years to obtain normal land line service there.

I notice that I* uses L-band around 1616 to 1626 MHz. As I recall, GPS and Radio Astronomy are both within 200 MHz below this. I don't know what frequency range G* is using.
