The Power & Accuracy of GPS
Wrist-top GPS technology provides the most accurate speed & distance data, especially over rugged terrain or when stride varies. The Discover includes an HRM (heart rate monitor) and PC analysis software allowing you to download AND upload entire routes using Google Earth. Perhaps best of all - Discover our price!
How It Works
There is a 24-satellite network which travels around the earth's lower orbit and is used by the Discover GPS watch to locate one's position anytime, anywhere in the world. The Discover has a GPS sensor that is a signal receiver and picks up satellite data transmissions as they are sent to earth. It takes at least four GPS satellites to do the job. As different satellites have different locations relative to the receiver, the watch computes the time gap between when the signal is transmitted and when it is received.. This time gap is used to locate one's position in three dimensions. Once a user's position has been determined, the watch can further compute information such as the current, average and maximum travel speed, distance and compass heading.
