The awesome processes that happen behind your back whenever a GPS receiver makes a query is what makes this technology well funded. This fast response is very beneficial to businesses, thus time and accuracy is of major importance. GPS as a tool is invaluable. But when asked, can anyone easily explain what GPS is and how does it work?
The story behind the GPS system is how the satellites measure the range or distance between one another and the receiver. In a way, it becomes a triangulation of some sorts, though because this is a spatial dimension; it looks more like an inverted pyramid. Satellites act like eyes in the sky. You may get lost in a forest because you couldn’t see anywhere in the horizon but trees, but if you had a vision of yourself from above the forest, you’d know where to navigate because there isn’t anything blocking your view. Using satellites to track your location is a novel idea in itself.
First, the satellites have an internal atomic clock that ensures everyone keeps the same time for even over a century with only a few nanoseconds off beat. The system monitors data that also involves the satellites’ location in latitude and longitude and others like height. This data is relatively important to your query as well, so it is important for the system to take note.
