My Google-Fu only leads me to a few dead-ends.

What is Ground Station, and why is the only reference to it in the manual regarding how it is disabled in sports mode.

I have found a DJI groundstation website, which seems to be something litchi-like, but none of you have mentioned it on this forum or elsewhere....????? Puzzled!

and no I haven't pushed it to find out - not til i know what it does....

There is a DJI Ground Station app, it's is in Beta testing.
more details will be announced when available.

Sweet! Cheers Ken :-)
