Perhaps rover orientation is only updated for driving/imaging etc at each new site number. I would have thought that they would use any and every orientation update possible ( and any sun observation would be able to do this ) - if for no other reason than good HGA pointing for uplink each morning.

My recollection is that the HGA only requires something like +/- 2.5 degrees precision in pointing, and the drift in the rover orientation quaternion stays well within that over multiple drives. It would certainly simplify navigation from my perspective if they would recalibrate daily, as even half a degree of drift complicates long baseline photogrammetry. |
