The Ground Station software is a lot different then what's in the DJI app for the P2. It's not in the Pilot app as DJI rushed the P3 to market before a lot of things were completed. I'm mean, a ton of things.
Though I see little new for GS on the P3 as it can be flown with complete control a mile away. GS flying was very limited in that the drone only recorded in the direction it was flying.
