Let’s start with the basics. Your fitness watch uses GPS — or Global Positioning System — to determine your exact location through a process called triangulation.
“Triangulation is a way to determine the difference between the time that your running watch receives a GPS signal and the time that GPS signal was sent to your running watch. The difference between sending and receiving a GPS signal determines how far away the satellite is,” explained Dan Lund, Product Marketing Manager of TomTom, to Digital Trends.
That process gets repeated with satellites that sit further away from the watch receiver, which pins down its exact location and continues to track the receiver throughout the activity.
“By integrating GPS technology in a fitness or sports watch, the watch measures a series of points that are used to accurately derive metrics like distance, speed, and pace. These metrics give runners real-time insight into their running performance,” Lund added.
What about elevation?
Elevation information is available via GPS just like horizontal position, but Lund and Garmin Product Manager Joe Heikes says the data is typically very noisy, and usually calculated through a website or app using a digital elevation model.
