GPS STATUS
Information related to your GPS signal can be checked in the GPS Status area. Your GPS signal can be set to Active or
Off. The current accuracy of your position is estimated in meters. The GPS must be locked onto a minimum of 4
satellites for full operation. Accuracy improves as the device locks onto additional satellites. Also displayed is the exact
location of your position in Latitude and Longitude notation (i.e. degrees, minutes, seconds) and the current altitude, as
calculated by the Joule GPS barometer.

TIP: Your current location is listed as a latitude and longitude pair. The numbers making up the pair are in
degrees, minutes, and seconds. The letter associated with the number is a compass point, North, South, East,
West. When viewing a map, latitude lines run horizontally; longitude lines run vertically, converging at each
pole, widest at the equator.
Lines of Latitude are numbered from zero degrees to 90°, north and south. These numbers can be
subdivided into minutes and seconds for greater granularity. 0° Latitude is the Equator, the imaginary line that
divides the earth into north and south hemispheres.
Lines of Longitude, also numbered in degrees, subdivided in minutes and seconds. 0° Longitude is the Prime
Meridian, established 1884, an imaginary line that runs through Greenwich, England. From the Prime
Meridian, the lines of Longitude run 180° east and 180° west until they meet in the Pacific Ocean, making up
the imaginary line known as the International Date Line.
Using the Latitude/Longitude numbered pair you can describe any location on Earth. In fact, the example in
the menu above is the location of Saris Cycling Group, near Madison, Wisconsin.
