Orpheus was a commercial satellite owned by Ra's al Ghul.
Ra's al Ghul launched the Orpheus satellite a year before his plan was to be executed, and it played a vital role in it. Planning to set off bombs at several Lazarus Pits around the globe, Ra's needed Orpheus to relay the detonation signal. However, Orpheus' location—in geosynchronous orbit over the Sahara desert—led Batman to Ra's hideout. Although the satellite was out of the Dark Knight's reach, he managed to shut off communications to it.
