What can possibly go wrong when you rely on satellite-based GPS for navigation?
Satellites and mobile networks
The map of where you are, on the other hand, comes with your app. Typically this map is updated live via the mobile network or wifi as you move along. Both of these aspects can affect how well the app works and explain why, ironically, it can be less reliable in a big built-up city than in Australia's outback.There can be one of two errors when your mapping app doesn't work correctly, says Dr Tregoning
The other error is that your position can be wrong — which means that the phone hasn't got the right information from the satellites to work out where you are.The GPS that we know and love is one of many global navigation satellite systems whizzing around overhead right now.At least four satellites are required to pinpoint your location, and this is easily achieved in most of Australia, says Dr Tregoning.
