Why would wind have any effect on a drone still locked onto 11 satellites?
Imagine you can row your boat at 6 mph .... but you are out on a river that's running at 8 mph.
Or perhaps the river is running at 4 mph ... but you get exhausted (your battery runs down) before you get home.
It won't matter how many satellites your GPS has or how hard you row .. you just aren't getting back home in that boat.
Here are some info about flying in high winds that might be useful.
1. RTH will initiate 3 seconds after loss of control signal
RTH will never descend until right above the home point. If your Phantom is higher, it will come home at the higher altitude.
Wind speed is always significantly higher at altitude than ground level. There are ways to get a feel for this to avoid losing your drone.
2. RTH is a slow driver. It cruises at 22 mph but you can drive at 36 mph (still air speeds).
If the Phantom is in RTH and trying to push against a wind stronger than 22 mph, it's going to be blown backwards until battery level triggers autolanding
It's very important to be aware of wind strength and direction.
Note how much the wind slows your Phantom if you try to fly directly into it.
Never fly away downwind in a strong wind situation - you will have a tough headwind to fight to get back home.
Never leave your Phantom up high fighting a headwind. Bring it down where the wind is less.
