Low‑power mobile GPS moving‑map display demand
Problem
Implementing real‑time GPS moving‑map display on resource‑constrained legacy hardware requires addressing low‑power computation, limited bandwidth for real‑time data transmission, and projection errors.
Pain points
- Implementing real‑time moving‑map on low‑clock‑frequency processors
- Transmitting real‑time GPS data over low‑bandwidth mobile networks
- Reliance on crude trigonometric approximations causing positioning errors that need optimization
Questions to verify
- Are there companies or developers who have implemented real‑time moving‑maps on similar low‑power hardware?
- What specific requirements do users have for real‑time GPS data transmission over low‑bandwidth networks?
- What tolerance level do users have for positioning errors introduced by crude trigonometric approximations?

One of the things I discovered a while back is that even fairly crude trig approximations don't put that much error into your position, over a small enough distance. To calculate things like straight-line range from where you are now to where you need to put a unit for an emergency, you're probably not working over an area of more than a couple of hundred kilometres radius and the error will be within a few dozen metres. And once you get within about half a k, you're driving towards the column of smoke anyway ;-)
