G* in the far North . . .

I tried to do a little research on the subject of Globalstar service in northern latitudes, and here's what I dug up:

From Lloyd's site-
"Globalstar is designed for 100% single satellite coverage between ±70° latitude, and 100% dual or higher satellite coverage between 25° to 50° latitudes. Globalstar will employ path diversity combining to mitigate blocking and shadowing; up to three satellites may at any one time be used to complete the call."

50N latitude ain't that far north. All of the UK is north of 50, along with much of Europe. Iceland is about 64N. Sounds like a lot of potential G* users may not get the benefit of path diversity.

Who would want G* service north of 70 degrees ? Well, Murmansk is a major port, and that is about 70N. Also, most of Greenland.

How about today's rumor of satellites for Santa ? Maurice is quite right that you can't have a geostationary satellite over the poles, but there is such a thing as a polar orbit, and by putting the sats in a higher orbit, and/or using an elliptical orbit, they can be made to "linger awhile". (that's the title of a song from 1923 that could be used for TV commercials in Murmansk.) Whether or not G* phones could commucicate with a sat in a higher orbit or not, I don't know. Maybe.
