PanAmSat's Galaxy IIIR Satellite Operating Normally on Secondary SCP

Apr 23, 2001, 01:00 ET from PanAmSat Corporation

   GREENWICH, Conn., April 23 /PRNewswire Interactive News Release/ --
 PanAmSat Corporation (Nasdaq:   SPOT) today announced that the Galaxy IIIR
 domestic satellite experienced the apparent failure of its primary spacecraft
 control processor (SCP), which caused the satellite to automatically switch
 control to its back-up SCP.  Normal satellite operations were restored through
 the use of the back-up SCP.  PanAmSat and the satellite manufacturer, Boeing
 Satellite Systems Inc., are continuing to investigate the apparent failure.
     A Boeing 601 spacecraft launched in 1995, Galaxy IIIR experienced the
 failure of its primary SCP at 2:40 p.m. Eastern time on April 21 causing a
 temporary outage of some C-band and Ku-band transponders.  Normal operations
 were restored to the satellite within two hours, during which time some
 customers experienced brief interruptions of service.
     In response to satellite technical issues, PanAmSat implemented a
 comprehensive satellite expansion and restoration plan in 1998 that includes
 the launch of four new Galaxy spacecraft as replacements for satellites that
 could suffer SCP failures.  As part of this plan, PanAmSat is set to launch
 the fourth satellite in the series, Galaxy IIIC, during the third quarter of
 this year to serve as the replacement for Galaxy IIIR at 95 degrees west
 longitude.
     Boeing has previously concluded that SCPs on Boeing 601 spacecraft
 launched prior to August 1997 contain tin-plated relay switches that can
 experience electrical shorts when several factors are concurrently present.
 The PAS-4 Indian Ocean Region satellite experienced the failure of its primary
 SCP in November 1998 and continues to provide normal service on its backup
 SCP.  PanAmSat plans to launch PAS-10 in May to serve as the replacement for
 PAS-4 at 68.5 degrees east longitude.
     "PanAmSat took immediate and successful action to assure the highest level
 of service for all our Galaxy IIIR customers," said Robert A. Bednarek,
 PanAmSat's executive vice president and chief technology officer.  "In
 addition, our on-going satellite expansion and restoration effort has afforded
 us the capability to offer unparalleled backup and redundancy for our
 customers."
