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

Mark: Thanks for taking the time to post those informative comments. You answered many of the questions that have come up in this discussion. I am especially pleased to get your verification on the orientation angles.
Now that we know that we are converting the quaternion data correctly, the only question remaining in my mind is how accurate is the final orientation. I did a little more digging around in the Analyst's Notebook and discovered that a "Get Quick Fine Attitude" was performed on sol 2164 and that there were only two subsequent drive attempts (one on sol 2165 and the last on sol 2169). These drives were attempts to improve the rover's northerly tilt for the coming winter. The mission Manager's reports indicate little improvement was achieved. I am going to conclude that the final orientation is accurate, since there were only two attempts to move the rover after the final QFA. I also found this nifty little map attached to the documentation from those sols showing Spirit pointing to the heading we expected. -------------------- ...Tom
