rtk gps module
The RTK GPS module represents a significant advancement in precision positioning technology, offering centimeter-level accuracy for various applications. This sophisticated system utilizes Real-Time Kinematic positioning, which enhances standard GPS capabilities by comparing data from a base station with a rover unit. The module processes carrier phase measurements and corrects atmospheric errors in real-time, achieving positioning accuracy of up to 1-2 centimeters horizontally and 3-5 centimeters vertically. The system consists of two main components: a base station that remains at a known fixed position and a rover that moves with the user or vehicle. Through continuous communication between these components, the RTK GPS module can provide precise positioning data at update rates of up to 20Hz. The technology incorporates multiple satellite constellation support, including GPS, GLONASS, and BeiDou, ensuring robust performance and reliability across different geographical locations. Advanced error correction algorithms and multi-frequency capabilities enable the module to maintain accuracy even in challenging environments. The system's ability to process complex positioning calculations in real-time makes it invaluable for applications requiring precise navigation and positioning data.
