   The Global Positioning System ( GPS ), originally Navstar GPS, [2] is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. [3] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near ...

3. Map matching - Wikipedia

   en.wikipedia.org/wiki/Map_matching

   Map matching is the problem of how to match recorded geographic coordinates to a logical model of the real world, typically using some form of Geographic Information System. The most common approach is to take recorded, serial location points (e.g. from GPS) and relate them to edges in an existing street graph (network), usually in a sorted ...

   Real-time kinematic positioning. Real-time kinematic positioning ( RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. It uses measurements of the phase of the signal's carrier wave in addition to the information content of the signal and relies on a single reference station or ...

6. GPS tracking unit - Wikipedia

   en.wikipedia.org/wiki/GPS_tracking_unit

   A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position ( geotracking) to determine its location. [1] Satellite tracking devices may send special ...

7. Satellite navigation - Wikipedia
