GPS Watch – A Great Tool to Help You Get More Out of a Sport

Recording your journey via GPS (Global Positioning System) represents a great way to get more out of a sport. It can help you train in the right zones, measure the miles you’re making and map where you have been for you. It also measures speed and distance accurately and there is no need for wires or sensors.

GPS receivers are able to convert speed, time and location information into a useful display using computing power and data stored in memory such as road maps, points of interest, topographic information and much more.

A group of satellites in the earth’s orbit which transmit precise signals, allow GPS receivers to calculate and display information to the user regarding the correct geographical point, speed and time. By capturing the signals from three or more satellites (there are more than 31 satellites available) the receivers are able to use various mathematical principles to tell you where you are.

The most versatile of the GPS units, and maybe the most useful, is the GPS watch. Some of the models include an integrated stopwatch, compass, barometer, altimeter and thermometer functions. Fitting the GPS technology into a wrist-top device that is easy to use and doesn’t use a lot of power takes creativity and ingenuity.

Models vary as well as the features, but in general, they aim towards hikers, climbers, bicyclists, boaters, and adventurers. You can also wear it for swimming, running and many other activities.

A GPS watch is more accurate than other devices if you need to measure your strides, and doesn’t need any supplemental wires or in-shoe sensors. It may also be linked to computer software and websites, which makes it possible for you to upload and analyse data, providing complete, easy to update and access training logs.

They work accurately in any environmental condition, day or night, around the clock and around the globe, also there is no subscription fee for use of GPS signals. However, some locations may not allow accurate GPS navigation. Their signals could be blocked by dense forest, canyon walls or skyscrapers and they don’t penetrate indoor spaces well.

GPS receivers are generally precise within 15 meters, and newer models using Wide Area Augmentation System signals reach this within three meters.

Today there are many manufacturers that can offer you the GPS watch to suit your type of activity. Simple and useful, a GPS watch can make a big change in the way you approach your training and a massive difference to your fitness levels if you didn’t have one.
