The new D-RTK 3 Multifunctional Station integrates high-performance antennas and receiver modules capable of tracking and resolving data from major global satellite navigation systems, and it supports multiple data transmission links. With these outstanding features, it can serve as a base station to provide centimeter-level positioning for multiple drones simultaneously or extend the operational range of drones in relay station mode. Additionally, the new rover station mode, combined with the DJI Enterprise app and DJI Terra, provides a comprehensive solution for high-precision aerial surveying applications, ensuring a secure and accurate operation.
