The only issue I am aware of, as far as the Wookong is concerned, is that version 5.24 has issues, and it appears it may be limited to v1 GPS. That thread has the words "WARNING" in the title.

I thought the solar storms were also causing issues with the GPS?

There is a thread about "2 major crashes" (that's in the title) that had a lengthy side topic about GPS and solar activity. There was another post about parts of Europe being affected by a jamming exercise (I forget that thread title).. Since solar flares and GPS jamming are not a Wookong specific issues, and you posted the question under the Wookong category, I thought you were talking about specific issues with that FC.

Monday again...
Good morning!

I Think that people tend to rely too much on GPS, Im nothing to do with software and how the gains algorithms affect the position hold...
But if you have a handheld GPS and you can see in your computer how a GPS with fix jumps all time (in the better scenario) in a circle you then can imagine how Wookong try to obtain from this data a place to maintain... then... in the manual, if I remember correctly they mention 2 meters circle aprox... until now, so far, it's wonderful to see how the S800 stands steady in the air... if you think all that is involved!

I do not know if everyone gives the necessary importance to the correct assembly of each of the components that will later be the "brain" of the autopilot, including that make us attach the IMU with double sided tape... if the adhesive fails in flight... the controller will act inmediately trying to fly a hanging loose IMU!...

Also, some of us also have flown our hexas without knowing exactly how the different flight modes behaves, what they mean or works, then when something fails is really difficult to trully understand the real causes of a crash...

I think I can ensure that any function that requires knowing the geographical position of the hexa not work or work terribly wrong if we can not read the flashes emitted by the strobe indicating GOOG GPS, or at least have a laptop with GS soft linked clearly telling us that all is "GOOD"...

since I have the WooKong so far I couldnt ever read the strobe lights... I prefer to read GS screen, for sure.

If I am right, flying in Manual(never) or Atti mode... RTH, IOC, or anything depending on GPS fix will not work...
Also including fail safe RTH function if you doesnt have GOOD GPS FIX all time.

Also if you have a faulty or obstructed barometer IMU unit you cant maintain an altitude hover position... due to bad atmosphere pressure reading.

Its a pity that DJI only can read the logs if we havent iOSD, must be many answers there.

I hope I have been able to contribute to the general confusion.
:)

Put it on perspective... you have an "aircraft" there flying autonomous... incredible!
