Oldgateboatdriver said:OK. Time perhaps to provide some people with an Arctic perspective, in layman's term and unclassified version (available to any one who researches it even superficially):
Satellite communication in the Arctic, especially the high Arctic is not the same easy-peasy one available in the South (and even in the South we can lose it in bad weather - see Videotron ads against Bell Satellite). It can still be pretty dicy at times. So for RPA's, you may have to rely on something closer. Best bet if UHF, but that means very short distances, and hence tonnes of towers to set up, man and maintain.
Moreover, with the magnetic North Pole smack in the middle of the North-West Passage, other navigation systems become unavailable. Those same magnetic currents that give us wonderful Auroras also play havoc with all sorts of electronics up there.
Finally, RPA's are good at looking down, but not so great at looking all around them at the horizon. Up in the Arctic, you can see the weather change drastically faster than you can say "HollydelabricamollyBatman!", and it is unforgiving even with humans present. Sorry. you just lost an expensive RPA.
Without wishing to derail the thread, that's the case for satellites in geostationary orbit. Satellites in non-geostationary orbits (low earth orbit or highly elliptical orbit, for example) can and do provide highly reliable communications in the very high Arctic ... but there's a price. A combination of business and technical/legal (agreements made in e.g. the International Telecommunications Union which have the force of treaty law) considerations mean that many LEOs must operate with only limited spectrum which means (relatively) narrow band channels. Service considerations may mean using a very large number of satellites (66 in the case of Iridium, for example) which means high costs, too.
There are good, effective ways to communicate into/out of and within the high Arctic, but they all cost money.
