Potential error for converting lat/lon to roll/pitch #319

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Arducopter V2.2 b4 (latest code)

What steps will reproduce the problem?
Looking at code in Arducopter.pde.

What is the expected output? What do you see instead?
In the function update_trig, lines 1781 and 1782, the first element (a.x) of 
the DCM matrix is taken to be sin(yaw) and the element b.x is taken to be 
cos(yaw).

I just looked at the DCM matrix that we are using and thought that it should be 
the other way round, with the a.x element being cos(yaw) and b.x being sin(yaw).

Please let me know if I am mistaken or is this an error that should be fixed? 
Thanks!
