Once [Moving base] is started and update the little “home” icon on the flight data screen:

  • Will RTL return to launch or to “home” position?

Thank you.

RTL will return to launch. MP never updates home, this was by design. however you can update rally point 0 with will make it return to your moving base location. assuming you have rally points setup.

Thank you for answering,

I did try to click on the “update rally point 0” tick box ,this was ok.

When placing a rally point on the flight plan screen, ok.

rally points are not available on copter. I assume that’s what you re using. the next copter release should include rally points however.

Thank you for answering.

Yes, using arducopter 3.3.3. Is Arducopter 3.3 Rc-1 working with rally points then?

Hi Michael,

Recently a client asked if it was possible to have a moving base so the plane could return to that point as they are launching the plane from a moving vessel. I was given the project and reading all the MP documentation I got my rally point 0 working and updating its position. The only issue I have is that when switching to RTL the GPS unit for the moving base is showing its Absolute Altitude and we are always working on Relative Altitude, when switching to RTL the plane moves to the rally point but increases its altitude due to the discrepancy of the altitudes. I tried the commands ATL_HOLD_RTL and RTL_ALT but they don’t override the rally point 0 altitude given by the GPS unit. It’s there any other way I can fix this so RTL maintains its current altitude when moving to rally point 0?

We are working with
MP 1.3.62
Pixhawk Cube 2.1
FW Arduplane ChibiOS V3.9.5

Hi Julian,

Have you tried in “Flight PLan” to set the RP alt to zero?
