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

Tom, I played around with rover quaternions years ago, I was never totally convinced I had got it working exactly right but comparing my code with the maths on calculator you posted I think you need to swap the last two elements over. Then you get numbers close to what I get from code I've used in the past to automatically generate panoramas with flat horizons.
heading -50.58337307972186 degrees attitude 8.761900410435159 degrees bank -17.565753444479686 degrees I'm not sure what the -50 for heading refers to as Spirt was facing very close to north, I have only every been interested in the pitch (attitude) and roll (bank) numbers which are about right I think. -------------------- |
