SAN DIEGO, CA, November 7, 2007 — Telemetry-West (L-3 Telemetry-West), a division of L-3 Communications, announced today that after supporting Astrium’s successful launch and initialization of Skynet 5A for the UK Ministry of Defence (MoD), its I4Ssatellite command and control software is now operational in both the Skynet 4 and Skynet 5 Satellite Control Centres (SCCs).  The I4S system is based on L-3 Telemetry-West’s InControl software suite integrated with Inmarsat’s in-house-developed software.  InControl is a robust system leveraging many years of operational satellite support and is specifically designed to support satellite fleets of heterogeneous spacecraft.  Having supported the launch and early orbit phase (LEOP) for Skynet 5A, I4S will continue to support the on-station operations for both Skynet 4 and Skynet 5.

“This achievement demonstrates the continued success of InControl as the leading software system for the safe and efficient monitoring and control of satellite fleets,” said Burt Smith, President of L-3 Telemetry-West.  “We are delighted to continue our successful relationship with Astrium on this important and strategic program.”

“Astrium is firmly committed to leveraging commercial systems into the military arena, capitalizing on sophisticated functionality at affordable prices without compromise to any military values,” said Colin Paynter, Managing Director of Astrium.  “The launch and early orbit phase is a crucial part of the mission.  It is vital we have software systems that are completely reliable and in which we can have absolute faith.  The L-3 InControl software suite, integrated with the Inmarsat real-time kernel, gives us a system that manages the LEOP phase very effectively and then transitions smoothly to routine operations with the same system.”

The Skynet 4 and 5 installations add to the number of SCCs L-3 Telemetry-West and Inmarsat support throughout the UK.  These systems provide secure communications for the UK’s armed forces, with Skynet 5 significantly expanding this role.

Key features of the InControl software suite include routine satellite fleet and ground station control, use of flexible open system standards, such as CORBA, Java and UNIX, and single or multiple operator control of multiple entities.  Archiving, archive retrieval and data analysis are also integrated within the functionality.

Skynet services have been taken over from the UK MoD by Paradigm Secure Communications.  Building on Skynet 4’s existing telecommunications capabilities, Skynet 5 delivers a secure global communications infrastructure.  The program provides a range of services that are used by the UK's armed forces, government departments and other agencies and organizations requiring secure communications.  These services are also available to approved defense and other governmental users from overseas countries and multinational organizations.
