| D-RTK 3 Multifunctional Station | |
|---|---|
| Overview | 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. It supports multiple data transmission links and can analyze device position and orientation through its built-in high-performance inertial measurement unit. 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, offers a one-stop solution for high-precision aerial surveying applications. |
