In 2002, the satellite's main spacecraft control processor failed, prompting DirecTV to move the spacecraft into a storage orbit. [27] The satellite was recalled in October 2003 and leased to Telesat, relocating to 82° W in order to provide backup for Nimiq 2. [28] In 2004, the satellite was relocated to 91° W, backing up Nimiq 1.
A satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit .
