CC, global mobile satellite services provided by Inmarsat and others use GEOs. Typically, you need a laptop size or bigger user terminal weighing several pounds and costing 3-4K$ and pay air time charges in the 2-3$ range for these services.

Within the next year, two new GEOs with higher power/bigger antennas will be launched that will permit use of handsets that look and cost more or less like G*. One is ACeS for service in Asia, the other, called Thuraya, will service the mid-East. They say they will be cheaper than Globalstar, but in addition to voice delays, they have a couple of other deficiencies compared to G*:

1. By nature of GEO orbit, the spacecraft are over the equator and at a specific longitude, making the useful service regionally limited

2. The (separate) programs each plan to launch only one satellite, so they can't tolerate any spacecraft failures. G* as you probably know can suffer multiple satellite failures without any significant degradation of service.

So, G* satellites are about 878 or 879 miles "up." Right ?

(Just hoping someone will check my arithmetic).

Jon.

G* holds this advantage over Inmarsat, which is a GEO based system.
