  2. Real-time kinematic positioning - Wikipedia

    en.wikipedia.org/wiki/Real-time_kinematic...

    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]

  3. GNSS applications - Wikipedia

    en.wikipedia.org/wiki/GNSS_applications

    Surveying — Survey-Grade GNSS receivers can be used to position survey markers, buildings, and road construction. [6] These units use the signal from both the L1 and L2 GPS frequencies. Even though the L2 code data are encrypted, the signal's carrier wave enables correction of some ionospheric errors.

  4. GNSS enhancement - Wikipedia

    en.wikipedia.org/wiki/GNSS_enhancement

    Real-time kinematic positioning (RTK) is another approach for a precise GPS-based positioning system. In this approach, the determination of the range signal can be resolved to a precision of less than 10 centimeters (4 in). This is done by resolving the number of cycles in which the signal is transmitted and received by the receiver.

  5. Surveying - Wikipedia

    en.wikipedia.org/wiki/Surveying

    Early GPS observations required several hours of observations by a static receiver to reach survey accuracy requirements. Later improvements to both satellites and receivers allowed for Real Time Kinematic (RTK) surveying. RTK surveys provide high-accuracy measurements by using a fixed base station and a second roving antenna.

  6. 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.

  7. Free stationing - Wikipedia

    en.wikipedia.org/wiki/Free_stationing

    When setting up the total station on a known point, it is often not possible to see all survey points of interest. When performing a resection (free stationing) with the total station, bearings and distances are measured to at least two known points of a control network .

  8. Deformation monitoring - Wikipedia

    en.wikipedia.org/wiki/Deformation_monitoring

    A radio telemetry wireline extensometer monitoring slope deformation. Deformation monitoring (also referred to as deformation survey) is the systematic measurement and tracking of the alteration in the shape or dimensions of an object as a result of stresses induced by applied loads.
