March 6, 2006

SAN DIEGO, CA, March 6, 2006 – L-3 Telemetry-West, a division of L-3 Communications, announced today that is has signed a contract with Orbital Sciences Corporation to provide the satellite command and control ground system software for the THOR II-R satellite, which is owned and operated by Telenor Satellite Broadcasting, a division of Telenor Broadcast Holding AS based in Oslo, Norway. L-3’s software solution is based on its InControl-NextGeneration™ (InControl-NG) system, which will be used to operate the new satellite and to control Telenor’s existing THOR II and THOR III spacecraft.

THOR II-R will be based on Orbital's STAR™ satellite platform and will provide Ku-band fixed telecommunications and direct-to-home television broadcasting services from Telenor's 1-degree west longitude orbital location. The Telenor fleet will utilize primary and back-up control centers in Fornebu and Nittedal, Norway.

“Orbital is pleased to welcome L-3 Telemetry-West as a part of our Thor II-R Program Team,” said Al Lewis, Orbital's Thor II-R program director. “We look forward to building on our successful past space hardware relationship with L-3 Telemetry-West to now include the delivery to Telenor of an industry-leading fleet system using InControl-NG.”

“Orbital’s selection of L-3’s InControl-NG system continues to affirm our regained share in the satellite command and control software business,” said Burt Smith, president of L-3 Telemetry-West. “We are confident that our technology is unsurpassed for today’s market needs.”

A key feature of the InControl-NG software includes the ability to execute multiple procedure languages to preserve the investment in operations procedures. In addition, the software’s integrated fleet operation capability offers a common control interface across a disperse fleet, system “status at a glance,” as well as the ability to quickly drill down to satellite-specific status and control.
