Oversimplified: GPS calculates position using precise timestamps transmitted from the satellites. It's completely based around time. The satellites have atomic clocks in them to maintain accuracy.

Do you?

yeah but it's not the only way for a device to get a signal to help sync it's clock.

You mean an alternative signal like WWVB in Colorado USA / MSF in Cumbria UK? There are signal deadzones all over; if you can see the sky you can receive the GPS signal.

Regardless, your initial post seemed to lack understanding of how GPS works. Time is the crux.

Yes, but it has 0 need for leap second adjustments, it's the relative timestamps between the satellites that matters, not their absolute values. (T1 + 18) - (T2 + 18) is still T1 - T2.

Way to miss the point just to act superior.

Way to misinterpret which person was acting superior.
