> As an aside, I have been unable to get my hands on any modern multi-frequency GPS receivers. If someone has a link to one that I can buy with a credit card, I would love it!
Try SwiftNav or Tersus. I have not used either of them so I can't comment on the quality, but $1-2k for an RTK setup is pretty great. They are both more 'startup' than traditional suppliers.
uBlox F9 looks good but isn't quite available yet. They have a solid line of single frequency receivers so I'm looking forward to seeing pricing.
I have briefly tested some Unicorecomm from China, and they work well, but they miss your online store requirement, and the documentation is nonexistent.
I'd suggest Yocto is the de facto standard for this kind of embedded device. It's a bit complex behind the scenes but general building and updating packages is fairly straightforward.
Bringing up the edison is very easy. The bootloader supports DFU, so you can simply connect USB, reset, and flash the system images.
If you're coming at it from a higher level, it has a node.js and ssh services running by default, so it's easy to start tinkering.
The Pandora [1] is a few years old at this point. I had one for a short while and wasn't too impressed. There will be an update called the Pyra [2] coming later this year.
