Sorry if this has been discussed anywhere but I can't seem to find much information about it - why is it that Voyager's pointing is so haphazard, as in this video of all the RAW Jupiter images - https://www.youtube.com/watch?v=bf5QJ8iFxUs?
I came across this link which says that pointing information for the images exists - http://pds-rings.seti.org/voyager/ck.html, but have also read on this forum that it's not very accurate. Would the information be useful in automatically aligning composite images and mosaics, or is it too coarse? Would it at least be useful in getting general alignments that could be refined by hand? And does anyone know why the cameras could not be pointed more accurately, or why accurate information could not be returned with the images? I assume it was some technical limitation, but just curious what it might be. |

The north azimuth that can be determined using the C kernels is accurate enough (and this applies to all of the Voyager C kernels) and this makes the available Voyager C kernels highly useful. The pointing itself (i.e. the location of the subspacecraft point in the image) is typically off by ~100 pixels and needs to be corrected. The C smithed kernels are an exception (they are much more accurate) but they are only available for the Voyager 1 Saturn images.
