ISS Second Loop QPD orientation of pitch and yaw signals now corrected
The orientation of the ISS second loop qpd was rotated 90 degrees and reversed in sign when compared to the orientation of IM4 Trans QPD.
I changed the QPD matrix and tested the change by exercising IM1 in pitch and yaw.
I've updated SDF.
Details attached.
