You can already get the FPV camera on the Inspire standalone (looks like the O3), but I doubt it will improve targeting capabilities much. The FPV link is 720p, unless they changed something, but I wouldn't be surprised if they use analog cameras which cost $10.
Maybe not targeting but the follow up BDA reports. Instead of having to send in a second drone to see the bomb damage, the same system can be used! Also, no need to wait for timing of a satellite pass over either.
