Any geostationary sat would be low on the southern horizon in Alaska. That's just how geostationary orbits work, they are over the equator. Though pretty high above (35.000km/22.000mi). So it's still visible there but yeah you need a clear view of the southern horizon. But Globalstar which runs the service for SPOT only has low earth orbit sats which are definitely not geostationary. They're only at a few hundred kilometers. However it could very well be that their orbits are aligned so that they are always pretty low to the south from Alaska, yes.
