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 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.

4. Networked Transport of RTCM via Internet Protocol - Wikipedia

   en.wikipedia.org/wiki/Networked_Transport_of...

   The Networked Transport of RTCM via Internet Protocol (NTRIP) is a protocol for streaming differential GPS (DGPS) corrections over the Internet for real-time kinematic positioning. NTRIP is a generic, stateless protocol based on the Hypertext Transfer Protocol HTTP/1.1 and is enhanced for GNSS data streams.

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. Fast Kalman filter - Wikipedia

   en.wikipedia.org/wiki/Fast_Kalman_filter

   The fast Kalman filter (FKF), devised by Antti Lange (born 1941), is an extension of the Helmert–Wolf blocking [1] (HWB) method from geodesy to safety-critical real-time applications of Kalman filtering (KF) such as GNSS navigation up to the centimeter-level of accuracy and satellite imaging of the Earth including atmospheric tomography.

7. 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.
