Detecting GPS jamming with planes actually works a lot better than from a fixed terrestrial object, because 1. They have greater sensor range, 2. There are lots of them, 3. They move and cover lots of area, 4. they cover e.g. parts of the Black Sea where it would be more difficult to put a ground-based sensor.
