RTKlar

RTKlar is a software system used for real-time kinematic (RTK) GPS positioning. It is designed to provide highly accurate location data in real-time, typically with centimeter-level precision. This accuracy is achieved by using a base station that transmits correction data to a rover receiver. The rover then uses this data, along with its own GPS measurements, to calculate its precise position relative to the base station.

The system is commonly employed in applications where exact positioning is crucial. These include surveying, construction, precision agriculture, autonomous vehicle navigation, and drone operations. RTK technology works by measuring both the carrier phase and the code phase of the GPS signals. The carrier phase measurements are more precise but are prone to cycle slips, which are momentary losses of lock on the signal. RTK algorithms are designed to resolve these ambiguities and correct for them, thus enabling centimeter-level accuracy.

RTKlar software typically processes the raw GPS data from both the base and rover receivers. It handles the complex mathematical calculations required to determine the relative position, taking into account factors such as atmospheric delays and satellite geometry. Users interact with RTKlar through a graphical interface or command-line tools to configure the system, monitor its performance, and log the resulting position data. The software often supports various communication protocols for data transfer between the base and rover, such as radio modems or cellular networks.
