RTK, or Real-Time Kinematic, is a satellite navigation technique that enhances the precision of position data. It uses signals from Global Navigation Satellite Systems (GNSS) to provide accurate location information, often within a few centimeters. This technology is widely used in fields like geodesy, surveying, and agriculture for tasks that require high accuracy. The RTK system typically consists of a base station and one or more roving receivers. The base station collects satellite data and sends corrections to the rovers, allowing them to calculate their precise positions in real-time. This capability is crucial for applications such as autonomous vehicles and drone navigation.
