Galileo

The point is control: GPS is operated by the US Space Force and GLONASS by Russia, while Galileo is civilian and EU-governed. Accuracy is in practice better than GPS thanks to three signals and very precise atomic clocks, and the free High Accuracy Service delivers decimetre-level positioning with no subscription. Every modern phone receives Galileo, GPS, GLONASS and BeiDou at once and combines them — more satellites in view means a faster fix and better results in urban canyons. The system also carries a Search and Rescue function that acknowledges a received distress call back to the beacon.
