I see this as well. It is now far enough away that I need to override and do a manual landing. As much as a few yards.
I don't fully understand home point identification. I have heard many talk about the drone taking a downward image of some sort as the home point is updated. Yet that doesn't seem to matter at all. If this happens, how exactly is this home point snapshot utilized in guiding the MA2 to it's original take off point?
Hi Lee,
Precision Landing (PL) is activated when a craft does a only vertical take-off and craft is stopped at approx 7 meter height ** and stopped for a while.
A scan is made of the terrain and stored. [ ** MA2 value ]
RTH uses compass and GPS to fly back above the HomePoint coordinates, PL activated or PL not activated.
Due to the sometimes not very accurate GPS data craft is not always exact above the take-off spot, but in my flights (always good GPS data and reception) never really far form the take-off spot (few inches to max 10 inches)
With PL activated it will scan the terrain during landing and if it matches to the stored scan than, if nessesary, craft will adjust its position to perform a precision landing.
A message on the screen does inform the user that craft is making a precision landing correction.Message in the log = "Precision Landing__Correcting Landing Position", cannot find a screenshot (yet) how this message is seen in the app.
EDIT just checked in the flyapp on my MA2, it does perform a precision landing but no messages on the screen and no correction messages in the log
Note
- When during flight HP is set to a new postion, PL will not work as the stored image will not match the terrain of the new HP.
- Important is that the terrain must have sufficiently distinctive features.
2 examples, MA and P4prof (using GoApp not FlyApp)
cheers
