  2. 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 Space Force and operated by Mission Delta 31. [ 3 ] [ 4 ] 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 ...

  3. Indoor positioning system - Wikipedia

    en.wikipedia.org/wiki/Indoor_positioning_system

    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.

  4. Satellite navigation - Wikipedia

    en.wikipedia.org/wiki/Satellite_navigation

    The United States' Global Positioning System (GPS) consists of up to 32 medium Earth orbit satellites in six different orbital planes. The exact number of satellites varies as older satellites are retired and replaced. Operational since 1978 and globally available since 1994, GPS is the world's most utilized satellite navigation system.

  5. GPS signals - Wikipedia

    en.wikipedia.org/wiki/GPS_signals

    A GPS receiver processes the GPS signals received on its antenna to determine position, velocity and/or timing. The signal at antenna is amplified, down converted to baseband or intermediate frequency, filtered (to remove frequencies outside the intended frequency range for the digital signal that would alias into it) and digitalized; these ...

  6. Real-time kinematic positioning - Wikipedia

    en.wikipedia.org/.../Real-time_kinematic_positioning

    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]

  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. Wi-Fi positioning system - Wikipedia

    en.wikipedia.org/wiki/Wi-Fi_positioning_system

    Wi-Fi positioning system (WPS, WiPS or WFPS) is a geolocation system that uses the characteristics of nearby Wi‑Fi access points to discover where a device is located. [1]It is used where satellite navigation such as GPS is inadequate due to various causes including multipath and signal blockage indoors, or where acquiring a satellite fix would take too long. [2]

  9. Assisted GNSS - Wikipedia

    en.wikipedia.org/wiki/Assisted_GNSS

    When applied to GPS, it is known as assisted GPS or augmented GPS (abbreviated generally as A-GPS and less commonly as aGPS). Other local names include A-GANSS for Galileo and A-Beidou for BeiDou. A-GPS is extensively used with GPS-capable cellular phones , as its development was accelerated by the U.S. FCC 's 911 requirement to make cell phone ...
