Propulsion Subsystem

Assembly

Gets the satellite to its slot and holds it there: a chemical engine raises the orbit, then electric thrusters fight the drift that would otherwise carry it away. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
