GPS watches use a network of GPS satellites to accurately track the distance and how fast you’re running or biking anytime and from any location. It’ll measure your average speed and maximum speed. It will calculate your average pace and best pace, tracks your workout distance, and also functions as a constant odometer.
GPS watches give enormous benefits to athletes who want to know their speed, pace and distance of their workouts. Contrary to basic sports watches, GPS watches should acquire and sustain at least 4 or even more satellite signals to be able to calculate the precise location. Some latest GPS watches have the ability to connect to twenty satellite signals at a time and while GPS is now more effective, this will drain lots of power from its battery.
Generally you could expect about 8-12 hours of persistent GPS use, based on the watch and its battery power. The different model GlobalSat and Garmin Forerunner watches give an internal, rechargeable battery and are able to run the GPS watches for about 8-10 hours, while Polar, Timex and the Suunto sports watches use an external GPS pod that takes AA batteries and lasts for 10-12 hours.
Most GPS watches enable you to turn the GPS off whilst running the normal sports functions and some have power saving modes that could reduce battery drain considerably. One such power saving option is to reduce GPS improving frequency. Rather than improving your location info every time, you can configure your GPS watch to improve every 5 or 10 seconds. This will decrease the precision of real-time measurements; however will extend your GPS watch usage time significantly.
Another power saving function would be to turn off EGNOS and WAAS which are location correction technology that improves the accuracy of GPS watches by locking onto non-GPS satellites that supply more correct information. WAAS for example improves GPS precision from within fifteen meters to within 7.6 meters. With WAAS turned off you’ll get much less accuracy; however the GPS would not consume battery power locking onto non-GPS sat networks.
Although, these power saving attributes are not often needed unless you’re contending in ultra-endurance event, they’re there whenever you need them. More particular data on GPS battery information can be found on our website.
Depending on the reason for your GPS watch, the information is recorded in the GPS watches memory and the longitude, altitude and latitude of your position are displayed. The data may then be downloaded to laptop or computer and could be analyzed and manipulated to be used in training, fitness and exercise. The info gathered could be used to note the distance traveled, speeds rate as well as other useful reports. Some kinds of GPS watches enable the monitoring of heart-rate, and speed of foot as well as other physical facts concerning the exercise and training. This is generally achieved with the help of accessories to the GPS watch.
There are two basic tasks that power of GPS watches has utilized. What we’ve discussed so far is a type of personal tracking of oneself. The further use that is becoming a growing industry is tracking somebody else. This utilize although very useful, is a lot less desirable to people who value privacy.
