Reply to comment by Electricpants 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

Yeah ofc, but 16 of the 31 GPS satellites that are currently operational have actually been launched after the start of Galileo in October 2011, and the oldest of the other 15 was launched in 1997. Also, they get software updates from time to time.

There may be a limit to how much you can increase accuracy on a system while maintaining compatibility with an old standard.
