1. This document provides a tutorial for using RTKLIB software to perform real-time kinematic (RTK) positioning. 2. It outlines steps to download the RTKLIB package and sample data, load configuration files, specify input data streams for the rover and base stations, start the RTK processing, view the solution on a map, and monitor the RTK status. 3. The tutorial demonstrates using RTKLIB's RTKNAVI and RTKPLOT programs to perform RTK positioning with sample GPS data and obtain an accuracy of centimeters.
