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]
NTRIP was developed by the German Federal Agency for Cartography and Geodesy (BKG) [3] and the Dortmund University Department of Computer Science. [4] Ntrip was released in September 2004. [5] The 2011 version of the protocol is version 2.0. [6] NTRIP used to be [7] an open standard protocol but it is not available freely (as of 2020).

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.
Ideally small changes in the measured data will not result in large changes in output location. The opposite of this ideal is the situation where the solution is very sensitive to measurement errors. The interpretation of this formula is shown in the figure to the right, showing two possible scenarios with acceptable and poor GDOP.

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.
