It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. [4] It does not require the user to transmit any data, and operates independently of any telephone or Internet ...
Vehicle navigation on a personal navigation assistant Garmin eTrex10 edition handheld. A satellite navigation device or satnav device, also known as a satellite navigation receiver or satnav receiver or simply a GPS device, is a user equipment that uses satellites of the Global Positioning System (GPS) or similar global navigation satellite systems (GNSS).
Navigation with Gosmore, an open source routing software, on a personal navigation assistant with free map data from OpenStreetMap. An automotive navigation system is part of the automobile controls or a third party add-on used to find direction in an automobile.
GPS encodes this information into the navigation message and modulates it onto both the C/A and P(Y) ranging codes at 50 bit/s. The navigation message format described in this section is called LNAV data (for legacy navigation). The navigation message conveys information of three types: The GPS date and time, and the satellite's status.
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.

A GPS receiver in civilian automobile use. Air navigation systems usually have a moving map display and are often connected to the autopilot for en-route navigation. Cockpit-mounted GNSS receivers and glass cockpits are appearing in general aviation aircraft of all sizes, using technologies such as SBAS or DGPS to increase accuracy.
GPS/INS is commonly used on aircraft for navigation purposes. Using GPS/INS allows for smoother position and velocity estimates that can be provided at a sampling rate faster than the GPS receiver. This also allows for accurate estimation of the aircraft attitude (roll, pitch, and yaw) [citation needed] angles.
Vehicle OBD tracking systems make use of OBD GPS trackers that plug into the onboard diagnostic (OBD) port of light, medium, or heavy-duty vehicle. A cellular OBD GPS tracker directly communicates with the cell tower for sending the location and other vehicle performance data to the server over the cellular wireless network.
