  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. Satellite navigation software - Wikipedia

    en.wikipedia.org/wiki/Satellite_navigation_software

    Satellite navigation software is most commonly used on mobile devices, particularly mobile phones, to provide the positioning functionality. However, relying exclusively on GNSS data is not accurate enough due to the limitations of GNSS services, To address this, Assisted GNSS (A-GNSS) is used instead.

  4. 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.

  5. 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).

  6. Satellite geodesy - Wikipedia

    en.wikipedia.org/wiki/Satellite_geodesy

    More sophisticated methods, such as real-time kinematic (RTK) can yield positions to within a few millimeters. 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 ]

  7. StarFire (navigation system) - Wikipedia

    en.wikipedia.org/wiki/StarFire_(navigation_system)

    StarFire is a wide-area differential GPS developed by John Deere's NavCom and precision farming groups. StarFire broadcasts additional "correction information" over satellite L-band frequencies around the world, allowing a StarFire-equipped receiver to produce position measurements accurate to well under one meter, with typical accuracy over a 24-hour period being under 4.5 cm. StarFire is ...

  8. Systems Tool Kit - Wikipedia

    en.wikipedia.org/wiki/Systems_Tool_Kit

    Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated environment. [1]

  9. 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.
