Real-time kinematic positioning

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] It uses measurements of the phase of the signal's carrier wave in addition to the information content of the signal and relies on a single reference station or interpolated virtual station to provide real-time corrections, providing up to centimetre-level accuracy (see DGPS).[2] With reference to GPS in particular, the system is commonly referred to as carrier-phase enhancement, or CPGPS.[3] It has applications in land surveying, hydrographic surveying, and in unmanned aerial vehicle navigation.
