Land mode without gps

PX4 Autopilot
1

Hello,
I am flying in altitude flight mode without GPS.

When I switch to LAND MODE it’s not working.
I need manually throttle down and disarm.

Is there any settings to be done for land mode without a GOS module?

Thank you

You need position for Land mode.

Same as "Land" flight mode without GPS - #2 by JulianOes

@JulianOes

Can I know why LAND mode in px4 requires position?

Based on height(barometer) it can decrease the vehicle altitude where ever it is.

Please help me to understand

Thank you

What you mean is called Descend and it’s only an emergency mode. Land assumes that you don’t want to drift away with the wind but stay on the same spot/position horizontally.

What do you mean by “Descend”? I need to implement an auto -land as a failsafe when battery is low. How to make it work even with no GPS available?

You need to use previous available position coordinates and trigger landing
