The Global Positioning System, GPS in current language, has now become a trusted companion of many hikers and bikers thanks to the inclusion of the cartographic vision that makes it similar, at least in the vision, to the familiar "maps", but with much more information.
Almost always, however, the "instruction manuals" of the electronic tools are clear and comprehensive in the theory, but often hardly understood in common use; We at TREKKING & Outdoor have decided to provide a simple but precise handbook on the use of this important "companion" of the hiker with practical examples that lead us to the discovery of new itineraries. We have chosen to present a series of advice on the most common situations and the most frequent questions asked by our readers.
My friends are waiting for me at home, I have promised them to take them to a special place but I need the help of my GPS. In order not to waste time, turn on the GPS and place it on the window sill while you prepare everything you need for the trip. The instrument will start acquiring the satellites and once arrived on the road, in a few seconds, it will be ready to "guide you" to the destination.
The Altimeter GPS app uses the integrated barometer of your iPhone (available from iPhone 6S or higher). It shows useful indications such as atmospheric pressure and weather forecast based on the barometer.
The data displayed are the result of the sensors in the mobile device, ie the GPS and the barometer. If the latter is not available in the terminal, the data will be less accurate as the app will be based on data from local weather stations, if available.
On Garmin GPS it is possible to activate tracks as routes simply indicating them as a destination for the "where to go" function. Normally the tracks will be navigated in the direction in which they were recorded, having to reverse the direction, you can act directly on the track from the management menu "track manager" and then activate them as a route.
