A data pusher is the most common type of GPS tracking unit, used for asset tracking, personal tracking and vehicle tracking systems. Virtually every cell phone is in this mode per user agreement, even if shut off or disabled storing the data for future transmission.
GPS data mining: It is possible to aggregate GPS data from multiple users to understand movement patterns, common trajectories and interesting locations. [123] GPS data is today used in transportation and disaster engineering to forecast mobility in normal and evacuation situations (e.g., hurricanes, wildfires, earthquakes). [124] [125] [126] [127]
Geopositioning can be referred to both global positioning and outdoor positioning, using for example GPS, and to indoor positioning, for all the situations where satellite GPS is not a viable option and the localization process has to happen indoors.

A cellular telephone in the automobile may then communicate with a traffic information server to obtain travel times ...
DGPS Reference Station (choke ring antenna)A reference station calculates differential corrections for its own location and time. Users may be up to 200 nautical miles (370 km) from the station, however, and some of the compensated errors vary with space: specifically, satellite ephemeris errors and those introduced by ionospheric and tropospheric distortions.
