I am trying to quantify Spirit's final resting orientation, but I would generally like to learn how to determine the orientation of either rover for any particular sol. I'm sure this data is in the MMB files somewhere, but I haven't been able to identify it. Likewise, I am sure it is somewhere in the Analyst's Notebook database and/or the Pancam data tracking database, but again, I can't find it.
Spirit's final orientation is the main thing I am looking for, but any orientation assistance would be greatly appreciated. Thanks. -------------------- ...Tom

I'm just following up on my own question. I found a quaternion calculator on line that supposedly could convert a quaternion into a set of angles in degrees. Using the rover quaternion from Doug's example above, it returned the following results.
CODE heading -12.658311877406014 degrees attitude -49.970826789740684 degrees bank -27.62979515200747 degrees Heading, attitude, and bank are apparently the equivalent of the aeronautical terms: yaw, pitch, and roll. A heading of about -12.7 degrees is slightly west of north, which seems reasonable. The attitude and bank angles are way too large to be reasonable for Spirit's orientation. I guess I have more work to do. -------------------- ...Tom
