This is just really confusing interface design and labelling.
The problem is that there's no such thing - in terms of "in game models" as a Satellite Installation (or indeed half the other types in the build menu). But, worse, the in game model names overlap with the Role names, so "Scientific Installation" is also a role.
If you look at it on the system map instead you'll see that it's giving you the benefits (wealth, etc.) of a Satellite Installation, not a Scientific one.
By analogy, a "courier" is both a mission type and a class of imperial ship, but you can do that mission type in any ship and can do any mission type in a courier.
