Intelsat 4 Satellite Experiences Anomaly

1 February 2010

Intelsat S.A. announced that its Intelsat 4 satellite (IS-4), located at 72° East Longitude, experienced an anomaly on 1 February 2010 at approximately 00:18 GMT.  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. 

Intelsat’s global fleet, the largest of any satellite operator, includes a number of other satellites that serve the regions formerly served by IS-4, providing a source of potential capacity for the restoration of affected customers. The failure of the satellite is not expected to impact significantly the company’s financial position or its planned capital expenditures.
