Product Description

Application Rangeļ¼š

Real-time kinematic (RTK) positioning is a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems, GNSS) such as GPS, GLONASS, Galileo, and BeiDou. 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. With reference to GPS in particular, the system is commonly referred to as carrier-phase enhancement, or CPGPS. It has applications in land survey, hydrographic survey, and in unmanned aerial vehicle navigation.



Usage:

GPS RTK GNSS consists of a base station, which monitors the signals coming from the satellites, one or several rover users to which the base station sends information, and a communication channel with which the base broadcasts correction data to the users in real time. RTK GNSS provides highly accurate positioning information within the vicinity of this base station.
