Gps Satellite
Why do we need to use relativity for GPS satellite systems?
Because their position in Earth's gravity well, and their speed, affect their clock rates. If they do not stay sync'd to similar clocks on Earth's surface, then we'd need to have arbitrary corrections of identical values... for no reason excape to make the values obtained, correct.
 
The GoTek8 Gps Tracker provides real-time GPS tracking using GPRS, has an emergency SOS button, works INSIDE buildings as well as OUTDOORS.
