Reply to comment by StrikeZone1000 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

True, but the oldest GPS satellite that is still operational was launched in 1997.

Also, 16 of the 31 GPS satellites that are currently operational have actually been launched after the start of Galileo in October 2011. Also, they get software updates from time to time.
