I don’t know your status of knowledge, so I apologize if I state the obvious.
Your issue is that of the co-registration of images.
You have to always decide what your “prime” or “truth” is. How was your “GIS” data precisely located? How do you know it’s not that which is off? (Even so, if you have “ground truth” measurements, they are usually more precisely located than remote sensing data.
Are the satellite images “map-projected” ? If so, against what ground truth was that projection performed? What geographical coordinate system of Earth was used for the map projection?
This stackexchange might help.
There are a bazillion books out there for that, don’t really have a recommendation, mostly learned my stuff by internet searches. ;)
HTH,
