I think I’m going to have to give up the whole fixed wing auto land feature…
The main issues are:
Constantly coming in way tooo high and long (overshoot).
Does seem to use or care about the TECS_LAND_ARSPD and the LAND_PF_ARSPD
I have changed the various parameters so many times it is crazy. I even started changing them in much greater increments. Alas, to no avail!
I have NEVER had a shorter than needed or expected landing sequence, never. No matter what I do the fixed wing (nano talon) always comes in to hot and too long.
My Glide Slopes never exceed -10 deg. I line up on several waypoints, all that - It just seems like it doesn’t want to ‘sink’ on the final approach! It will ‘sink’ or scrub altitude great when in an auto mission just flying a pattern but oohhhh no… do the DO_START_LAND approach thing and forget it… Long and Shallow baby, every time.
I think I must have at least 50 attempts at this over many days (and using the same approach pattern).
I have messed with the LAND_PF_ALT&SEC up as wel. Im just wanting or trying to get it to initiate the 'lock heading, address speed, and flare baby flare - but no, no real changes…
Any others having this issue(s)? I mean I’m not trying to pull off any acrobatics here, just a long, easy, approach and land.
… guess it wasn’t meant to be.
see a few you tube videos where people pull it off.
Even watched the hour long ardupilot auto landing seminar video (very hard to follow), printed out the overhead screens showing ideal & bad glide slopes. I reviewed all the settings called out there - again NOTHING has made this thing come in slowing down and on target.
