Reply to comment by TommyTuttle 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, but with GPS you can reach a maximum precision of about 20-30 cm (this signal is encrypted), while Galileo's encrypted signal provides about 1 cm. Note that these are the values that are possible to get almost instantly, and by only using a single signal band (with long-term measurements, and by using several signals, you can get a sub-millimeter precision with both GPS and Galileo)
