Aerobraking is when a spaceplane with wings and aerodynamic control surfaces adopts an egg shaped orbit such that when the craft has the most momentum it enters the upper atmosphere and has the ability to redirect momentum to a wide variety of vectors using flaps like a normal plane.

Yes satellites have their own propulsion often but it is nothing like this and is extremely limited comparatively.

The mission also builds on momentum from OTV-7. During that mission, the X-37B completed a first-of-its-kind aerobraking maneuver to change orbits while conserving propellant. That demonstration mattered because it showed how the platform can operate more flexibly in space, giving mission planners freedom of maneuver without sacrificing precious fuel.

A satellite is predictable most of the time, these are not.
