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. Satellite navigation solution - Wikipedia

   en.wikipedia.org/wiki/Satellite_navigation_solution

   Satellite navigation solution for the receiver's position (geopositioning) involves an algorithm.In essence, a GNSS receiver measures the transmitting time of GNSS signals emitted from four or more GNSS satellites (giving the pseudorange) and these measurements are used to obtain its position (i.e., spatial coordinates) and reception time.

4. Satellite navigation - Wikipedia

   en.wikipedia.org/wiki/Satellite_navigation

   GNSS-2 is the second generation of systems that independently provide a full civilian satellite navigation system, exemplified by the European Galileo positioning system. [5] These systems will provide the accuracy and integrity monitoring necessary for civil navigation; including aircraft.

5. Galileo (satellite navigation) - Wikipedia

   en.wikipedia.org/wiki/Galileo_(satellite_navigation)

   In 2004, the Galileo System Test Bed Version 1 (GSTB-V1) project validated the on-ground algorithms for Orbit Determination and Time Synchronisation (OD&TS). This project, led by ESA and European Satellite Navigation Industries, has provided industry with fundamental knowledge to develop the mission segment of the Galileo positioning system. [128]

6. GNSS software-defined receiver - Wikipedia

   en.wikipedia.org/wiki/GNSS_software-defined_receiver

   A software GNSS receiver is a Global Navigation Satellite System (GNSS) receiver that has been designed and implemented using software-defined radio.. A GNSS receiver, in general, is an electronic device that receives and digitally processes the signals from a navigation satellite constellation in order to provide position, velocity and time (of the receiver).

7. Satellite navigation device - Wikipedia

   en.wikipedia.org/wiki/Satellite_navigation_device

   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).

8. Quasi-Zenith Satellite System - Wikipedia

   en.wikipedia.org/wiki/Quasi-Zenith_Satellite_System

   Quasi-Zenith satellite orbit QZSS animation, the "Quasi-Zenith/tundra orbit" plot is clearly visible.The Quasi-Zenith Satellite System (QZSS) (Japanese: 準天頂衛星システム, Hepburn: juntenchō eisei shisutemu), also known as Michibiki (みちびき, "guidance"), is a four-satellite regional satellite navigation system and a satellite-based augmentation system developed by the Japanese ...

9. GPS signals - Wikipedia

   en.wikipedia.org/wiki/GPS_signals

   GPS signals are broadcast by Global Positioning System satellites to enable satellite navigation.Using these signals, receivers on or near the Earth's surface can determine Position, Velocity and Time (PVT) of the receiver.
