Maybe a simple homemade GPS mount can help. Mount your sat unit to your vehicle (if applicable and needed).Set the position-recording frequency to the highest possible, depending on the memory of your device, the foreseen length of your track, and the speed at which you're travelling.On Garmin devices, it's on the first page of the map setup. Check if your sat unit has a "Snap to road" or "Lock on road" option, make sure that option is switched OFF, or you will end up merely recording a direct copy of the map loaded into the sat unit, which is not only a copyright infringement (unless your map was downloaded or derived from OpenStreetmap, etc.), but is possibly going to be less accurate than the track you would otherwise record.If you need any help, please ask questions on the Mailing lists or IRC. Not all the steps may be necessary (or possible) on your particular device. The following guide therefore provides generic advise to help you get started. With hundreds of receiver devices available, providing detailed instruction for all of them is infeasible. See GPS Reviews for a list of reviews of receivers by OSM contributors. Away from a power supply the battery life tends to be quite short (often 3 hours or less).Ĭertain hardware receivers can emit raw data that can be post-processed to centimeter or decimeter accuracy using post-processing software. Although some can also record tracks, this is not true of all. With a large display, the main function of In-car SatNav devices is that of navigation. Apps can be installed to provide the ability to record tracks, provide navigation features, and even edit OpenStreetMap directly. The battery life can be 24+ hours (depending on screen use) and they are generally rugged devices that are splash-proof or waterproof.Īlmost all smartphones and many tablets include GNSS/GPS. Many also include a small screen for displaying maps, basic settings and accuracy measurements. These are small devices which are used to record track logs. The most useful for OpenStreetMap listed below.
There are many types of satellite receivers, from a simple logger to smartphones with embedded GNSS chip(s).
