  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. 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.

  4. GNSS enhancement - Wikipedia

    en.wikipedia.org/wiki/GNSS_enhancement

    A second form of precise monitoring is called carrier-phase enhancement (CPGPS). [1] The error, which this corrects, arises because the pulse transition of the PRN is not instantaneous, and thus the correlation (satellite–receiver sequence matching) operation is imperfect. The CPGPS approach utilizes the L1 carrier wave, which has a period of

  5. 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.

  6. Geodesy - Wikipedia

    en.wikipedia.org/wiki/Geodesy

    Real-time kinematic positioning (RTK GPS) is employed frequently in survey mapping. In that measurement technique, unknown points can get quickly tied into nearby terrestrial known points. One purpose of point positioning is the provision of known points for mapping measurements, also known as (horizontal and vertical) control.

  7. Error analysis for the Global Positioning System - Wikipedia

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

    For very precise positioning (e.g., in geodesy), these effects can be eliminated by differential GPS: the simultaneous use of two or more receivers at several survey points. In the 1990s when receivers were quite expensive, some methods of quasi-differential GPS were developed, using only one receiver but reoccupation of measuring points.

  9. Cadastral surveying - Wikipedia

    en.wikipedia.org/wiki/Cadastral_surveying

    Cadastral surveying is the sub-field of cadastre and surveying that specialises in the establishment and re-establishment of real property boundaries. It involves the physical delineation of property boundaries and determination of dimensions, areas and certain rights associated with properties.
