Why define gyro's data as acceleration and gps's second part as altitude

In ENU, the third value is altitude.

This is inherited from https://github.com/cyberbotics/webots/blob/master/projects/robots/dji/mavic/controllers/mavic2pro/mavic2pro.c, we should probably fix it.

@lukicdarkoo , I suggested to add webots simulation on PX4/PX4-Autopilot#18221. Do you have any advice ?

That would be lovely, but I am not sure whether it's our priority right now. Could you please create an issue in the webots repository?

BTW, there is already an ArduPilot integration:

Does PX4 depend on ROS? I see some launch files there, but I thought PX4 is standalone.

[dzywater]

PX4 is standalone.
It can communicate with the external by
(1)MAVLink protocol, e.g MAVSDK(a high-level API to MAVLink)
(2)MicroRTPS, a type of DDS
(3)ROS or ROS2, but this way is still by MicroRTPS
(4)MAVROS, similar with webots_ros2 principle
MAVLink and MAVROS are general and can be used for PX4 and ArduPilot.
See: mavlink/mavros#1369
I knew ArduPilot webots simulation.
I aslo want to have PX4 webots simulatio.

Hi, is there any progress on PX4 SITL in Webots? I cannot see the issue has been created.
