Prior to the merger, the Sirius Satellite Radio service operated with three satellites in a highly elliptical orbit.[18] Following the merger, the combined Sirius XM adopted XM's geostationary pattern,[18] though Sirius's original satellites remained in service until 2016, when they were decommissioned and placed into disposal orbit.[19]
