Archimedes
From Halopedia, the Halo wiki
Summary
A Remote Scanning Outpost located on the edge of the Sigma Octanus system, the Archimedes was designed to detect incoming threats to the Sigma Octanus System. It was crewed by three individuals. In 2552, the Archimedes detected a hostile Covenant force inbound for Commander Keyes' battle group. Ensign William Lovell worked aboard this station and, because of this incident, he was transferred to the Pillar of Autumn by Captain Keyes.
