PX4/Pixhawk Offboard Mode


(Ash) #1

Hello guys

I’m researching how to best fly the pixhawk with an on-board computer, while relying on some of the flight mode functions already built into the pixhawk such as altitude hold.

I have a down-looking lidar connected to the pixhawk and can perform altitude hold while flying with a radio. If I fly the pixhawk in offboard mode and use the on-board computer to send a height command through mavlink, will the pixhawk know to maintain altitude using this sensor?

This is what you’re looking for

Hello Luis, no i’m not looking for a list of companion computers. I’m trying to understand what happens to some of the automated control functions like altitude hold when pixhawk is switched to offboard mode.

ArduPilot has no offboard mode.

Instead you use Guided Mode and the commands can be issued via Mavlink from an external source, such as a companion computer. On the link I sent there is a page that sends to dronekit-python as a possibility, but ROS connections are also possible via MavRos
