It turns out you can get a location just by scanning nearby wifi and cell tower signals!

    GPS is a passive receiver.

    There’s processing going on, but you dramatically decrease energy use by just updating less often.

    It’s not like you’re sending a signal to space.

      I am aware of that but somehow expected that it still took more energy to receive until there are enough SATs available than to do a BLE scan. Just a gut feeling though and only receiving should have a bigger impact than I thought. Makes sense!
