RTK Survey
Request a QuoteReal Time Kinematic (RTK) satellite navigation is a technique used to enhance the precision of position data derived from satellite-based positioning systems, being usable in conjunction with GPS, GLONASS and/or Galileo. It uses measurements of the phase of the signal s carrier wave, rather than the information content of the signal, and relies on a single reference 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.[citation needed] It has application in land survey and in hydrographic survey The method of choice for a centimetre-accuracy site survey is RTK (Real Time Kinematic). RTK involves the use of 2 GPS receivers (stationary Base Station and a Rover) communicating together via a radio link. The base station must be located such that it will have a clear view of the sky and a continuous line-of-sight to the rover. The precision of the Rover position relative to the Base station is dependent on baseline-length so it is desirable to keep the baseline as short as possible (<10 km)..
