HOW IT WORKS
The website www.prealpiflash.it includes a descriptive summary of the itineraries described by Giovanni Carraro in the book “Prealpi Flash”, a photogallery of the individual stages of the routes, and a download section to get the GPS track you need. With this file you can study the itinerary data before leaving, thanks to one of the numerous GPS tracking software available on the market: highlight the altitude profile, calculate the length of the excursion, read the geographical points of departure and arrival, and display the route by comparing it with the underlying cartographic maps or satellite photos.
The file can be uploaded onto one of the numerous Apps available for smartphones or smartwatches; it can also be uploaded onto specific, more advanced, handheld or wrist-type hiking sat-navs. It will therefore be up to the hiker to decide which is the best device; the important thing is to always use the GPS track for all the itineraries proposed here.
GPS is a system used to determine the geographic position of an object on the Earth’s surface thanks to the signal sent by a network of orbiting satellites. The greater the number of satellites captured, the more precise the location will be.
A GPS receiver is a radio module inserted in GPS navigators. They are handheld or wrist-based, but can also be integrated into smartphones and smartwatches thanks to the dedicated App.
Some sat-navs contain cartographic maps that show your position. Many navigators can record our movement by generating a track that will consist of a file, usually with a .gpx extension that can be shared and loaded onto specific applications and then followed during the excursion.
A GPS navigator works independently from phone coverage. It doesn’t work if it doesn’t intercept satellite signals, for example inside homes, caves, tunnels, ravines, or in valleys with high rock walls.
The navigator picks up the signal from the satellite network and not vice versa. To launch an SOS signal, you need to let rescuers know your geographic coordinates via message, call or App, provided there is cellphone coverage.
In addition to receiving a GPS signal, some devices can send an SOS request using specific satellite networks such as the Iridium system, which however requires a paid subscription. In this case you don’t need cellphone coverage.
Sometimes the track to follow may appear imprecise, with deviation or zigzagging compared to the map (“drift” effect). This happens depending on the degree of accuracy of the satellite network which can provide an error compared to the real point based on the weather conditions, the availability and position of satellites in orbit at a given time, the quality and type of the GPS navigator used.
The altimetric function of the satellite apparatus is calculated on satellite triangulation. An inaccuracy of the signal can generate a deviation and therefore very often GPS navigators provide for the integration of a barometric altimeter that can provide greater accuracy.
Like all electronic devices, even GPS navigators have technical limitations. An example is the battery: if it runs out, we will no longer be able to know our position, so let’s not forget to put a map, the book, and a compass in our backpack.
