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 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 ...

3. GPS signals - Wikipedia

   en.wikipedia.org/wiki/GPS_signals

   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 .

4. GNSS applications - Wikipedia

   en.wikipedia.org/wiki/GNSS_applications

   GNSS applications. Global Navigation Satellite System (GNSS) receivers, using the GPS, GLONASS, Galileo or BeiDou system, are used in many applications. The first systems were developed in the 20th century, mainly to help military personnel find their way, but location awareness soon found many civilian applications.

5. Satellite navigation device - Wikipedia

   en.wikipedia.org/wiki/Satellite_navigation_device

   Satellite navigation device. A satellite navigation device, satnav device or satellite navigation receiver is a user equipment that uses one or more of several global navigation satellite systems (GNSS) to calculate the device's geographical position and provide navigational advice. Depending on the software used, the satnav device may display ...

6. GPS disciplined oscillator - Wikipedia

   en.wikipedia.org/wiki/GPS_disciplined_oscillator

   A GPS clock, or GPS disciplined oscillator ( GPSDO ), is a combination of a GPS receiver and a high-quality, stable oscillator such as a quartz or rubidium oscillator whose output is controlled to agree with the signals broadcast by GPS or other GNSS satellites. [1] [2] GPSDOs work well as a source of timing because the satellite time signals ...

7. 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 for GPS can increase accuracy by about a ...
