I doubt Windows on ARM will make any difference.
You may be able to find a dedicated program, but they're hard to come by as most PC's don't have GPS.
I'm not sure why you'd think that.
Snapdragon ARM chips come with GPS (and always connected LTE, instant on etc). The GPS part of the SoC is called "Qualcomm location", I believe. The inclusion of these features standard, the pricing, and the battery efficiency and size, are the points of difference over intel - they are essentially, from the consumer POV, "the point of the product" (Although no doubt for Microsoft, its more about UWP apps, mobility apps from developers AS WELL as having those smartphone like features to be competitive)
Due to both browsers (platform agnostic), and the UWP platform (which is designed to be platform agnostic), one doesn't need dedicated desktop software for GPS map applications. So one could use Sygic, or the native maps app, or google earth, or google maps in a browser.
All one actually needs is a standard compliant GPS module, and a standard complaint maps utility. This is why we have NMEA:

If you have any standard compliant GPS module, and any standard compliant GPS software, connected by a native driver (which of course arm devices will have), it will just work. Of course LTE enabled arm devices also have the advantage of speed up "warm up times" for location finding due to cell tower triangulation.
But if one didn't want to wait for ARM devices, one could just use a dongle like I link in the next post - which will work with google products.
