I really want to make sure that the altitude on this message is AMSL. According to common.xml it should be AMSL. To do that I searched the code for GLOBAL_POSITION_INT
and mavlink_msg_global_position_int_send
but I did not find the place in the code where that message gets assembled :frowning:

Can someone point me to the source file where that message gets assembled ? basically the function call to mavlink_msg_global_position_int_send or something equivalent

The mavlink message is sent here:

It is filled with the data from the uorb message, which is published here:

Looks like AMSL.
