GPS, n.Trivia

The first satellite used in GPS navigation was launched in 1989.

GPS is free for the world to use, it costs $2 million per day to operate. The money comes from American tax revenue.

Australia’s entire GPS navigation system was found to be off by 4 feet in 2016 when its satellite navigation systems failed to account for tectonic shift—roughly 2.2 inches a year over 2 decades—and threw everything slightly out of position.
