  2. 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).

  3. Personal navigation assistant - Wikipedia

    en.wikipedia.org/wiki/Personal_navigation_assistant

    Bicycle navigation on a personal navigation assistant. According to the analyst firm Berg Insight, there were more than 150 million turn-by-turn navigation systems worldwide in mid-2009, including about 35 million factory installed and aftermarket in-dash navigation systems, over 90 million Personal Navigation Devices (PNDs) and an estimated 28 million navigation-enabled mobile handsets with GPS.

  4. GNSS applications - Wikipedia

    en.wikipedia.org/wiki/GNSS_applications

    Survey-grade GNSS receiver industry include a relatively small number of major players who specialize in the design of complex dual-frequency GNSS receivers capable of precise tracking of carrier phases for all or most of available signals in order to bring the accuracy of relative positioning down to cm-level values required by these applications.

  5. 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.

  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 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.

  8. OmniSTAR - Wikipedia

    en.wikipedia.org/wiki/OmniSTAR

    Accuracy depends on satellite geometry, local conditions, receiver capability and other variables, but typically the L1-only solution (VBS - Virtual Base Station) yields horizontal accuracy of < +/1 meter > 95% of the time and the L1/L2 solutions (OmniSTAR HP, OmniSTAR XP or HP/XP combined) provide horizontal accuracies of < +/- 15 cm > 95% of ...

  9. Positioning system - Wikipedia

    en.wikipedia.org/wiki/Positioning_system

    A major subclass is made of geopositioning systems, used for determining an object's position with respect to Earth, i.e., its geographical position; one of the most well-known and commonly used geopositioning systems is the Global Positioning System (GPS) and similar global navigation satellite systems (GNSS).
