Thanks for this detailed response. As the THETA does not have a GPS chip inside of it, the developer would need to add an external GPS unit. I think there are two basic strategies:
- connect the GPS directly to the THETA V with USB OTG
- connect the GPS to a small board computer computer that is connected to the THETA
The cheapest GPS unit I can find is $16, which is cheap enough.
The problem is that people will need to buy an additional board to connect it to the THETA, either a USB breakout board or something like an Arduino.
I see bunch of Arduino boards for under $8 on eBay.
