  2. GNSS enhancement - Wikipedia

    en.wikipedia.org/wiki/GNSS_enhancement

    Utilizing the navigation message to measure pseudo-range has been discussed. Another method that is used in GPS surveying applications is carrier-phase tracking. The period of the carrier frequency times the speed of light gives the wavelength, which is about 0.19 meters for the L1 carrier.

  3. 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]

  4. 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.

  5. Position resection and intersection - Wikipedia

    en.wikipedia.org/wiki/Position_resection_and...

    Position resection and intersection are methods for determining an unknown geographic position (position finding) by measuring angles with respect to known positions.In resection, the one point with unknown coordinates is occupied and sightings are taken to the known points; in intersection, the two points with known coordinates are occupied and sightings are taken to the unknown point.

  8. Satellite geodesy - Wikipedia

    en.wikipedia.org/wiki/Satellite_geodesy

    In geodesy, GNSS is used as an economical tool for surveying and time transfer. [4] It is also used for monitoring Earth's rotation, polar motion, and crustal dynamics. [4] The presence of the GPS signal in space also makes it suitable for orbit determination and satellite-to-satellite tracking. Examples: GPS, GLONASS, Galileo

  9. Geodetic control network - Wikipedia

    en.wikipedia.org/wiki/Geodetic_control_network

    A geodetic control network is a network, often of triangles, that are measured precisely by techniques of control surveying, such as terrestrial surveying or satellite geodesy. It is also known as a geodetic network, reference network, control point network, or simply control network.
