As of 2026[update], the SiriusXM satellite radio service operates using a fleet of seven communications satellites in a geostationary orbit.

Decommissioned
Elliptical
Prior to the merger, the Sirius Satellite Radio service operated with three satellites in a highly elliptical orbit.[16] Following the merger, the combined Sirius XM adopted XM's geostationary pattern,[16] though Sirius's original satellites remained in service until 2016, when they were decommissioned and placed into disposal orbit.[17]
