GPS beacons would be stupidly expensive, as you'd need tens of thousands of them per city, and each one of them would need a very accurate atomic clock.
It would make far more sense (but still unviable) to go for Eurobalise-style RFID tags embedded in the road surface.

- Havoc 1y ago>you'd need tens of thousands of them per city I was thinking more find a tall building and throw a single one there. Or maybe tallest 3. As I understand it even a small number of extra satellites with line of sight can improve results a fair bit. So aiming at low hanging fruit rather than blanket city >very accurate atomic clock. Indeed, but I'd think managing that on ground is easier than in space.
- SpicyUme 1y agoWhat happens when the building sways multiple feet in the wind? We don't normally think about them moving, but for accurate positioning I'd think the additional distance to the beacon could be a problem.
- cyanydeez 1y agono, you arn't understanding. Those beacons would just be fixed places that know what their position is according to the GPS network. You're tihnking of someone tkaing a GPS sattilite and putting it somewhere.
