  2. 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 ...

  3. Real-time kinematic positioning - Wikipedia

    en.wikipedia.org/wiki/Real-time_kinematic...

    A surveyor uses a GNSS receiver with an RTK solution to accurately locate a parking stripe for a topographic survey. Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. [1] It uses measurements of the phase of the signal's carrier wave in addition to ...

  4. GPS signals - Wikipedia

    en.wikipedia.org/wiki/GPS_signals

    v. t. e. GPS signals are broadcast by Global Positioning System satellites to enable satellite navigation. Receivers on or near the Earth's surface can determine location, time, and velocity using this information. The GPS satellite constellation is operated by the 2nd Space Operations Squadron (2SOPS) of Space Delta 8, United States Space Force.

  5. Indoor positioning system - Wikipedia

    en.wikipedia.org/wiki/Indoor_positioning_system

    Indoor positioning system. An indoor location tracking map on a mobile phone. An indoor positioning system (IPS) is a network of devices used to locate people or objects where GPS and other satellite technologies lack precision or fail entirely, such as inside multistory buildings, airports, alleys, parking garages, and underground locations.

  6. Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Global_Positioning_System

    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 ...

  7. Precise Point Positioning - Wikipedia

    en.wikipedia.org/wiki/Precise_Point_Positioning

    Precise positioning is increasingly used in the fields including robotics, autonomous navigation, agriculture, construction, and mining. [2]The major weaknesses of PPP, compared with conventional consumer GNSS methods, are that it takes more processing power, it requires an outside ephemeris correction stream, and it takes some time (up to tens of minutes) to converge to full accuracy.

  8. Differential GPS - Wikipedia

    en.wikipedia.org/wiki/Differential_GPS

    Differential GPS. Transportable DGPS reference station Baseline HD by CLAAS for use in satellite-assisted steering systems in modern agriculture. Differential Global Positioning Systems (DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS can increase accuracy of positional data ...

  9. GPS aircraft tracking - Wikipedia

    en.wikipedia.org/wiki/GPS_Aircraft_Tracking

    GPS aircraft tracking is a means of tracking the position of an aircraft fitted with a satellite navigation device. By communication with navigation satellites, detailed real-time data on flight variables can be passed to a server on the ground. This server stores the flight data, which can then be transmitted via telecommunications networks to ...
