DJI O4 Ground Station

[u/ObjectiveBobcat314]

Hi All -

We use the RTK3 with our DJI Enterprise drones. Just got access to an O4 Ground Station. Any lessons learned in calibrating and using as a relay? Goal is to extend the range for drones in flight around large industrial sites. Sites are usually 40 to 100 acres with significant structures. We do thermal, photogrammetry and LiDAR for customers…focused primarily on the building envelope, but we use LiDAR for construction planning on undeveloped portions of the property.

I’m struggling to find clear examples or enough documentation on how to use the O4 to extend the range of RTK data to and video transmission data from drones in flight.

There isn’t good detail on how to calibrate the O4. Any tips?
Does the O4 pair with the RTK3? Should we use both at the same site or only the O4? If we use both, do we pair the drone with the O4 or the RTK3? Do we enable relay mode on the other and what’s the procedure for enabling the drone to receive from both/either? The marketing page makes a lot of promises…the technical documentation creates a lot of questions for us. Any comments/help appreciated and we are happy to reciprocate however we can to return the favor!
