DJI Launches O4 Ground Station: Wide-Area Transmission System Built for All-Weather Drone Operations
DJI has introduced the O4 Ground Station, a ruggedized ground communications system integrating a high-performance RF module, a 12-antenna omnidirectional array, and automatic multi-band switching. Compatible with DJI Dock 3 in either Gateway or Relay mode, it achieves a maximum transmission range of 40 km when paired with the Matrice 400, with a standby power draw of just 7 W — designed for large-scale, unattended drone operations.
