Now I understand !
Geez... I never understood the GPS system before and how it uses time to get my position. Now I understand! Seems that the satellite overhead is actually a clock which sends out a time signal. From this satellite and several others up in the sky, there’s triangulation for these intersecting time signals on the ground which in turn tells me how far along I am. Wow! Never understood before. Now, YES! Go there, you’ll be amazed like me.
