Reply to comment by 42gauge in TIL that the European Union developed a satellite navigation system called Galileo, which can provide an accuracy of up to 20 cm (0.7ft) on smartphones, while GPS only reaches around 3 meters (10ft) by apeowl
It still is. GPS satellites broadcast many codes for positioning. Civilians do not have access to military P(Y) or M codes which are far more accurate then the civilian C/A or L2C codes.
Your thinking of when they turned off Selective Availability, which is an intentional degradation of the C/A code to reduce accuracy.
