Can you give me a general description, of how GPS technology works?

GPS stands for Global Positioning System, and it is a collection of satellites and other technology that allows devices to determine their location on the Earth, and even track how they are moving.  The GPS satellites orbit the Earth, and each satellite has a built-in radio transmitter that constantly broadcasts its location.  If you have a GPS receiver, such as a smartphone, you can use this information to calculate your own position and distance from each satellite.  You can also use GPS information to track your movements, such as if you’re traveling in a car or on a hiking trail.

Sure! The Global Positioning System is an elaborate global network of satellites, ground stations, and radars.  
These satellites each transmit signals at the same time.  These signals reach each other at the same time as well.  The distances from the satellite to any two satellites are well known.  
So when an object receives two signals simultaneously, you know both of the distances.  By looking at the difference in time it takes for the signals to reach, you know the actual distance to the satellite.  
By looking at these distances to several satellites, you can triangulate your position on earth, and this is what the GPS device is doing.
