Everybody has heard this term, but how exactly does it work?

By Jesse Baker, CTB

With Technology rapidly advancing in the Transportation industry, it is important to understand some of the foundations for what is starting to become common place.  Today, we will focus on GPS.  Everybody has heard the term, but let’s dive in to exactly what it is and how it works.

GPS, short for Global Positioning System, uses three parts to help either ourselves or others locate where we are.  So what are these parts and how do they work?  Let’s check it out!

Satellites – Satellites, which orbit our earth, are in set positions.  Thus we can rely on them to give accurate feedback for location.  There are thousands of satellites available to be used by receivers.  This is where you have probably heard “triangulate their location” as 3 (or more!) satellites are being used to bring to a point the location of the receiver.

Receiver – The receiver is the device that sends out the signal to the satellite.  This is very commonly your phone, but can also be that new ELD or several other devices.  Once the receiver sends a signal to several satellites, it will calculate its distance from them and be able to diagnose an extremely accurate location!

Ground Station – The ground stations are the regulators for the satellites.  They make sure they have not drifted off course, and if they have, they adjust for the movement of the satellite so that the receiver’s calculations for location can stay accurate.

The great thing about GPS is how quickly it all works!  These waves move at unbelievable speeds, allowing accurate updates to be obtained as quickly as snapping a finger.  So if you are in the business of wanting to be accurate and quick in your updates to customers and wanting to keep them happy, then start utilizing the readily available GPS and improve your business as quickly as you are located!
