Every .waypoints file I save in Mission Planner has a first line that doesn’t show up in the GUI when editing a mission. Even if I save a completely empty mission, I still get this line:
QGC WPL 110
0 1 0 16 0 0 0 0 33.240922 -96.935463 162.000000 1
The command (16) is a waypoint, but the coordinates seem to correspond to a location I set as the home in MP.
What does this line do and how does it affect a mission?
Ari.
Its your home location
Thank you, @iampete. Is it a special case for the first line in a file that it isn’t a waypoint to fly to but the home location? Would using 179 MAV_CMD_DO_SET_HOME achieve a similar result?
Ari.
Its just a AP thinig, that is where it stores the home-location. A DO_SET_HOME would change the value.
Thank you.
I’m still trying to understand the home location, and it’s surprising to me how confusing I find it.
I fly at a club field that’s 20 miles away from my house. When I try to plan a mission at home, MP tries to set the home location to my house, which is useless.
But when I go to the field, AP sets home to where I arm it, which is usually in the pits (“1” in the picture). This is also useless to me. Club rules prohibit flying West of the runway. I could arm at the runway just before I launch, but that wouldn’t help either: in RTL, half the airplane’s orbit would be on the West side of the runway over the pits–exactly the kind of safety issue the rules are tying to prevent. I want set home well East of the runway–where the airplane can loiter without disturbing other traffic (“2” in the picture).
Am I thinking about all this wrong?
Ari.
So the recommendation is to forget about the home location and rely on rally point(s)?
Ari.
yeah, exactly the sort of thing there for.
Oh, that makes things simpler :=)
Thank you for setting me straight!
Ari.
