Real-Time Kinematic (RTK) is a satellite navigation technique that enhances the precision of location data. It uses signals from Global Navigation Satellite Systems (GNSS) to provide centimeter-level accuracy in real-time. RTK is commonly used in applications like surveying, agriculture, and autonomous vehicles, where precise positioning is crucial. The system works by comparing the data from a stationary base station to a mobile receiver. The base station calculates the difference between its known position and the position reported by the satellites. This information is then transmitted to the mobile receiver, allowing it to correct its position instantly.
