You should still have (oblique) views of the constellation above 55°N, partly due to the large altitude of the GPS satellites. But you're not guaranteed to have 12 satellites in view, so your solution may not be as accurate. There are polar regions where you probably do lose service. It's interesting (though not surprising!) that GLONASS has a slightly higher inclination.
- Andrew_nenakhov 4y agoIt was important for USSR/Russia to have positioning service available at high latitudes. Thus, higher inclination.
- nocoiner 4y agoGiven the initial customer of the GPS system, I would have thought full coverage of the USSR would have been a top priority.
- Andrew_nenakhov 4y agoI think that inclination is enough to provide such coverage. Maybe with somewhat reduced accuracy in the northern areas. Also, everything north of ~62°N is basically a wasteland.
- avtolik 4y agoDo polar explorers use some other navigational aides then? I wonder how inaccurate is the GPS really close to the poles.
