There are some satellites that can be scanned.
The scanned satellites yield data items required for engineering ship parts.
Imperial Capital ship dock next to Jefferies Port in the Ugrivirii system. There are also 3 satellites here that can be scanned again and again by relogging. Another thing of note here is that Jeffries Port has a great stock of equipment, seems like it is a major station. Scan all the military ships, they may well yield some nice data items. It could also be a good place to do some wake scanning on the military patrols. See also this video.
