SEAL BEACH, Calif.--(BUSINESS WIRE)--Nov. 19, 2001

DIRECTV-4S, a Boeing 601HP satellite built for DIRECTV Inc., is scheduled for launch on Monday, Nov. 26.

The satellite was built by Boeing Space and Communications, the world's leading satellite manufacturer and a business of The Boeing Co. (NYSE:BA). DIRECTV-4S will be the sixth Boeing-built satellite launched this year and the 61st Boeing 601 spacecraft launched to date.

DIRECTV-4S will be launched by Arianespace aboard an Ariane 44LP rocket from the Guiana Space Center on the northeast coast of South America. The 38-minute launch window opens at 9:35 p.m. at the launch site (4:35 p.m. PST; 12:35 a.m. Nov. 27 GMT).

DIRECTV-4S will be stationed with other DIRECTV satellites at 101 degrees West longitude. DIRECTV-4S is designed to provide the DIRECTV(R) digital satellite television service with more than 300 channels of additional capacity. DIRECTV will use that capacity to deliver additional local channels and to strengthen the redundancy of its in-orbit fleet.

"In addition to being the largest Boeing 601HP spacecraft we've built, DIRECTV-4S will also be a terrific example of leading-edge Boeing technology tailored to serve our customers' business needs," said Boeing Satellite Systems President Randy H. Brinkley. "Delivering local channels to individual TV markets is an important part of the DIRECTV service, and DIRECTV's ability to do so will be significantly expanded by the spot-beam technology we designed and built into DIRECTV-4S."

This will be the fifth Boeing-built satellite deployed by DIRECTV and the first spacecraft in the DIRECTV fleet to employ spot beams. This technology reuses the same frequencies on multiple spot beams to reach the major television markets where DIRECTV delivers the signals of local network affiliates.

"DIRECTV-4S and its Boeing spot beam technology is an investment that will benefit our customers and enhance our growth in the 41 markets where we offer local channels," said Roxanne Austin, president and COO, DIRECTV. "DIRECTV and the Boeing satellite manufacturing team have established an enviable record of technological leadership that continues to set us apart in the satellite television industry."

DIRECTV-4S will also be the world's first commercial satellite to employ high-efficiency solar arrays with triple-junction gallium arsenide solar cells built by Spectrolab Inc., a BSS subsidiary. These solar cells are called triple-junction because they employ a three-layered structure, with each layer able to capture and convert a different portion of the solar spectrum. The DIRECTV-4S solar cells will be able to convert 24.5 percent of the sun's energy into electricity. The spacecraft's two solar arrays are together designed to deliver 8.3 kilowatts of power at the end of its 15-year design life.

The spacecraft will carry two Ku-band payloads: spot beams for local channels, and a national beam payload. The spot beam payload will use a total of 38 traveling wave-tube amplifiers (TWTAs) ranging in power from 30 to 88 watts. The national beam payload will carry two active transponders with further capability for two active high-power transponders and six active low-power transponders.

Once deployed, the DIRECTV-4S solar arrays will measure more than 85 feet long from tip to tip, and its antennas will span 24.5 feet in width. The spacecraft fully fueled at launch will weigh 9,400 lbs. (4,260 kg).
