Posting this here now that is apparently real. OK. Here's what I think is in that video. First, all flight modes are impacted. Not just Ground Station or GPS! Unplugging the GPS will limit you to 394ft (120m).
Flight limitations system:
- Prevents Phantom from flying in restricted areas.
- In effect when there is sufficient GPS signal, mode independent.
- Cat A = Class B airports, 1.5 mile (2km) no fly zone, 5 mile (8km) safety zone, ceiling imposed at 35ft increasing to 400ft AGL.
- Cat B = Class C airports, 0.6 mile (1km) no fly zone.
- 0.6 m (1km) warning zone around restricted areas for Ground Station and Phantom Vision.
- No Ground Station waypoints within 5 miles (8km) from the center of any restricted area.
- If GPS position is above ceiling in safety zone, Phantom will descend to maintain ceiling.
- If GPS position is within no fly zone (e.g. acquiring signal after flying into it):
- Phantom will auto land.
- You can still control flight but you cannot climb.
Safety cone:
- Default of 1,300ft (400m) AGL, and 1 mile (1.6km) lateral distance.
- User adjustable (can someone confirm these are pretty much unlimited?).
- Ceiling of 394ft (120m) AGL imposed on flight without GPS signal.
So, xrover, you can fly at Marina del Ray and in Venice. You be under the cone so you will be height restricted but otherwise you should be fine.
