  2. Error analysis for the Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Error_analysis_for_the...

    When taken together, autonomous civilian GPS horizontal position fixes are typically accurate to about 15 meters (50 ft). These effects also reduce the more precise P(Y) code's accuracy. However, the advancement of technology means that in the present, civilian GPS fixes under a clear view of the sky are on average accurate to about 5 meters ...

  3. Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Global_Positioning_System

    As of early 2015, high-quality Standard Positioning Service (SPS) GPS receivers provided horizontal accuracy of better than 3.5 meters (11 ft), [7] although many factors such as receiver and antenna quality and atmospheric issues can affect this accuracy. GPS is owned and operated by the United States government as a national resource.

  4. Real-time kinematic positioning - Wikipedia

    Accuracy is increased in a CORS network, because more than one station helps ensure correct positioning and guards against a false initialization of a single base station. [9] A Virtual Reference Network (VRN) can similarly enhance precision without using a base station, [10] using virtual reference stations (VRS), instead. The concept can help ...

    At this confidence level, positional measurements are considered accurate enough to meet all but the most sensitive applications. 2–5 Good Represents a level that marks the minimum appropriate for making accurate decisions. Positional measurements could be used to make reliable in-route navigation suggestions to the user. 5–10 Moderate

  6. 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).

  7. Tractive - Wikipedia

    en.wikipedia.org/wiki/Tractive

    Tractive develops and sells GPS & Health trackers for dogs and cats that enable pet owners to view their pet's real-time location, receive Health Alerts, and monitor activity and sleep patterns via a smartphone app. Tractive tracks around 1,000,000 pets in over 175 countries worldwide using GPS and GSM technology.

  8. 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.

  9. 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.
