Create precise maps over large areas by attaching the RTK Module for EVO Max 4N/4T from Autel Robotics directly to your drone. Note that this requires an A-RTK base station (not included), but the module, combined with the base station, enables centimeter-level accuracy and utilizes real-time RTK technology and access to multiple GNSS constellations, including GPS, Galileo, and Beidou. Especially beneficial for agriculture and surveying professionals.
