Who needs satellites?
Once upon a time, before we had GPS, I worked briefly for a company developing and deploying a navigation/tracking system. Using not satellites, but land-based beacons, sending out the signals from which to compute a position. We would even track a live position and display it on digital maps, sourced (from memory) from Bartholomews in those pre-google-maps days.
I left that job in 1989. Sometime after that, they switched to GPS, thus dispensing with the expense of custom positioning infrastructure. But since money is now magic, we can just resurrect that 1980s infrastructure.
Then build our own mobile 'phones featuring the Great British Positioning System on a raspberry pi. Snub Apple, Samsung, and all those Chinese!
