I've just uploaded, but I must say, this seems to give less info than Airdata. It's missing some of the error messages and also doesn't show the message when the Home Point got updated, whilst thi sinfo does show on Airdata.
Anyway, here's the link; very happy to get any pointers. Wondering if the 13 sats was a combination of GPS, Bediou and Galileo systems, which could mean that no one system gave a proper lock....
Hi Ian
Thanks,
You started your flight with 13 satellites and 2 for GPS health or signal quality reception
GPS icon nust be coloured RED....
At 21.8s in flight GPS icon white, bc "health"now 4. With 4 or 5 HomePoint is set.
(check it in my chart of your data)
Rest of the flight always 13 sats and 4.
And check also the max height setting, wich is set to 30 meters and later in flight to your own max height setting (only possible with "good" GPS)
VPS height about 5.9 meter, Baro height about 8 meter.
So IMO not the GPS was the problem but flying above streaming water.
As said, hover instability due to bad GPS will not drift a drone from position is one direction.It will drift ofcourse on the wind in ATTI mode, but your drone was not in ATTI mode.
If i look at GoogleEarth, seems tha the drone move direction is the streaming water direction....
ADD : from 29.2s the VPS height sensor was not measuring....this until 43.6. So the height values 5.9 meters is not the actual height. ( it is copy paste from the last know height)
cheers
