AirSim + Cesium custom starting location - WARN [health_and_arming_checks] Preflight: GPS fix too low

[Snoeprol]

Question

What's your question?

I am having issues starting the simulation at a custom location. When I have no OriginPoint, there is no issues.

Now I only suspect one thing, that GPS and the location in the settings file and the location in the engine may be slightly misaligned. Could this really be it?

Otherwise, does someone else have any suggestions?

But as soon as I add:

    "OriginGeopoint": {
    	"Longitude": 4.902346,
    	"Latitude": 52.379172,
    	"Altitude": 10
    }

My drone will not arm and I have the following error:
