Intelsat 4 anomaly
February 3, 2010
A few days after Eutelsat's problems, Intelsat has announced that its Intelsat 4 satellite (IS-4), located at 72° East Longitude, experienced an anomaly on February 1st. Intelsat is working with affected customers to identify restoration capacity.
Intelsat and Boeing Space and Intelligence Systems, the manufacturer of the IS-4, are working together to identify the cause of the anomaly. Launched in 1995, the Boeing 601 satellite was expected to reach its end-of-service life later in 2010. Intelsat previously disclosed that the IS-4 had experienced the failure of its satellite control processor (SCP) and was operating on its backup SCP.
