RTKLIB is an open source program package for standard and precise positioning with GNSS (global navigation satellite system). RTKLIB consists of a portable program library and several APs (application programs) utilizing the library.
Using GNSS raw data, it is possible to do real-time and post-processing to accurately determine a position, using either a base station, precise point positioning (PPP) or precise ephemerides and clock data. The software supports all major satellite constellations (GPS, GLONASS, Galileo, BeiDou, SBAS, QZSS) and major file exchange formats. The toolkit runs with a GUI on Windows and command line tools on Linux.
With professional receivers and antennas, it is possible to achieve centimeter accuracy, while low-cost single frequency equipment can achieve decimeter accuracy.
Let's take a look at the performance of the TERSUS RTK board.
