Cablevision Launches Satellite

CAPE CANAVERAL AIR FORCE STATION, Fla. -- Cablevision Systems Corporation (NYSE: CVC) and Lockheed Martin (NYSE: LMT) announced that the Rainbow 1 telecommunications satellite was successfully launched today from Cape Canaveral aboard an Atlas V rocket provided by International Launch Services (ILS), a Lockheed Martin joint venture.

Cablevision Chairman Charles F. Dolan stated: "Today's successful launch of Rainbow 1, the world's most powerful and technologically advanced spot beam satellite, signifies an important advancement in Cablevision's history of state-of-the-art content delivery.

"Cablevision has always been focused on creating compelling programming and Rainbow 1 will allow targeted, nationwide distribution for that content, helping us to offer our service directly to the home. It is indeed a great day for the company," concluded Mr. Dolan.

"We are extremely proud of the total system solution we have delivered today for Cablevision," said Ted Gavrilis, president, Lockheed Martin Commercial Space Systems. "Our A2100 satellite and the ILS-provided Atlas V make a powerful combination for mission success, and we are proud to be part of launching a new direct-to-home service for Cablevision ."

Rainbow 1, a high power Ku-band satellite, will provide direct broadcast services across the continental United States (CONUS) from its final orbital location at 61.5 degrees west longitude. The spacecraft features 24 MHz Ku- band high power transponders with a combination of 135 watt and 65 watt power amplifiers. The flexible design of the payload provides full interconnectivity to provide either all CONUS or all spot beam coverage through 22 individually programmable spot beams or a selectable mixture of both spot and CONUS coverage. Rainbow is an A2100AX satellite, manufactured by Lockheed Martin Commercial Space Systems, Newtown, Pa., with a predicted service life of 18 years.

The A2100 geosynchronous spacecraft is designed to meet a wide variety of telecommunications needs, ranging from Ka band/broadband services to fixed satellite services in a Ku-band payload configuration to high-power direct broadcast services using the Ku-band frequency spectrum. The A2100's modular design features a reduction in parts, simplifying construction, increasing on-orbit reliability and reducing weight and cost.

In recognition of the A2100's reliability, Lockheed Martin has received a 2003 award for "Product of the Year," by Frost & Sullivan. Calling it "the most reliable and efficient of its class," Frost & Sullivan recognized the LMCSS-built A2100 satellite platform for its "outstanding on-orbit reliability record since it was first offered in 1996."

The Rainbow 1 mission is designated AV-003, signifying the third launch of the Atlas V, the most powerful in the Atlas vehicle family built by Lockheed Martin Space Systems. The Atlas II, III and V family of vehicles has achieved a record of 65 consecutive successful launches.
