Drone

This is the Mavic 3 drone. The wee bump on its back is an RTK GNSS receiver which allows it to position itself to a couple of cm in relation to a reference station. In this configuration the "correction" is coming from the tripod mounted Trimble receiver (The base). The correction reaches the drone by its radio communication with its controller and the controller in turn is connected by wifi to the base station. Alternatively, and with more convenience, a correction service can be tapped into by internet using a mobile phone as a hotspot. I had already tried that and the signal was so marginal that the correction was dropping out.
If there is a criticism of the DJI software it is impossible to save each set of configurations and I have resorted to a printed sheet. Miss a full stop or an underscore and it won't work.
The extra is a screen shot of the point cloud model from which I can continue and extract a more conventional looking contour plan.
