If each range of GPS uses its own interface making it difficult to describe precisely the steps to follow to set up, prepare its GPS for its hike in a single article, the methodology remains the same for everyone. To fully enjoy your GPS, you need a map to locate and a track (or waypoints) to be guided.
How to use a hiking GPS?
Principle of GPS
The Global Positioning System is a network of 24 satellites (originally) belonging to the US Army. With 12 satellites for the northern hemisphere and 12 for the southern hemisphere, it allows thanks to a GPS receiver (a hiking GPS for example) to get its position on land with an accuracy of ten meters. The receiver needs to pick up at least 4 satellites to determine its position. Today with our increasing dependence on GPS, and to face the competition, Americans are expanding their network (31 satellites to date) to improve the accuracy and reliability of the system. With the xy find it app, the navigation comes perfect.
By capturing two different constellations, GPS, these receivers make it possible to obtain better reliability and precision, especially when the receiver receives few satellites (at the bottom of a valley, in a dense forest, etc.). In 2020, Europe will have its own network called Galileo. Consisting of 30 satellites, it will offer a precision of a few meters and will be compatible with the EGNOS terrestrial network. Namely, China is also deploying its own system.
Use a hiking GPS
A hiking GPS can either be used as a main orientation tool or as a backup. In this second case, it essentially serves to position itself on a map, when one is lost for example. Just read the GPS coordinates that it indicates and transfer them on the map to be located immediately. It can also quickly transmit its position to help in case of problems.
