You probably can't.
Not sure of the relevance of that.
Your drone would fly perfectly well without any GPS in your controller.
The drone's GPS is the only one that matters for positioning, accurate home point and tracking.
I've never had one...
Here is a 100% crop from the central area, downrezzed to 25MP with bicubic sharper. ACR default conversion, photoshop 2025.
I have never seen a 20MP Mavic 3 / 3 Pro image from the 4/3 camera with this level of detail.
Obviously we need some...
No ... the GPS receiver in the drone is responsible for these.
Whether your controller has GPS or not makes no difference to flight safety.
That number is the number of sats your drone is receiving signals from - not the controller.
