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

Eduardo, do you mean for heading? I don't think that solar location would help very much for attitude. However, the Sun's position is an excellent reference for both heading & longitude computation.
EDIT: Apologies; upon further reflection, yes, you could indeed derive attitude data via solar observation, although it seems that considerable interpolation of not only the Sun's angle with the horizon but also its orientation within the frame would be required. But the IMU itself would almost certainly have to be the primary data source, so the question again becomes what sorts of references & error corrections are involved for IMU data interpretation. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
