No. But, this document states the following:aartsf said:Hay msinger,msinger said:Right -- no GPS required. Course Lock uses the compass to figure out which way it should be heading.
Did you test that realtime?
MC will record the current nose direction as forward direction at 30th second after you power on the multi-rotor.
And if you loose the compass... No course lock... So do this... Quadcopter Drone Orientation Tips for Distant Flying: http://youtu.be/qdYTCfjUVVomax said:Agreed, this is useful information to know. I can't think of a specific situation in which it would be useful, but still good to know! Loss of GPS and loss of FPV, and loss of visual orientation, but maintenance of control.
The statement doesn't say it is calculating nose-direction based on only compass input. Actually it would also not be possible to calculate (nose-) direction based on the input of only one source/antenne! It would a least need input from two sources /antennes that have sufficient distance between them to enable a 'revear cross-bearing', needed to calculate the nose-direction.

??? My understanding of a magnetic compass is it can single-handedly determine direction WRT magnetic north. Maybe I am misunderstanding you?
N017RW said:One way to visualize it is the classic grid analogy...
Once the CL heading has been stored during power/warm up that heading becomes the forward reference for CL flight.
Let's say the quad was facing due West, so that's its CL reference heading.
Now when in CL, no matter which direction the quad is facing (i.e. red banded arms) at the time of moving S2 into the middle position, pushing forward on the elevator or right stick will cause the quad to move due West.
Moving the right stick, aileron, to the right will cause the quad to fly due North and so on.
