Boeing Celebrates 10th Anniversary of the World's Best-Selling Satellite Model (photo)

ST. LOUIS, Aug. 14, 2002 -- The Boeing Company [NYSE: BA] marks the 10th anniversary today of the Boeing 601, the best-selling geosynchronous communications satellite model that has powered revolutionary changes in the way people around the world communicate.

From providing the platforms that launched DIRECTV and the satellite television broadcast industry in 1994 to Navy UHF satellites that support military operations in Afghanistan today, Boeing 601's have proven their remarkable versatility again and again. Seventeen customers in nine countries have ordered a total of 84 Boeing 601s built by Boeing Satellite Systems, the satellite design and manufacturing arm of Boeing Integrated Defense Systems, and they continue to leave an enduring mark on the shape of today's world.

The first Boeing 601 communication satellite, Optus - B, rocketed into orbit on Aug. 14, 1992. This spacecraft owned by Optus Communications Pty., Ltd., provided the far-flung Australian community with a range of services that included direct broadcast television, voice communications, digital data transmission, high-quality television relays and centralized air traffic control services. In addition, Optus B introduced the first domestic, mobile satellite communications network to Australia.

Since then, customers around the world have depended on Boeing 601 spacecraft to deliver a similarly diverse array of commercial, civil and government satellite services for them.

"The 601 satellite line's flexibility and power give our customers the solutions they need to meet their individual requirements," said Randy Brinkley, president of Boeing Satellite Systems. "We designed and built the 601 spacecraft with close attention to the long-term strategic needs of customers in both the commercial and military worlds and they continue to evolve and perform to keep pace with those demands."

The Boeing 601 was introduced in 1987 to meet anticipated requirements for high-power, multiple-payload satellites for such applications as direct television broadcasting to small receiving antennas, very small aperture terminals for private business networks, and mobile communications. The basic configuration features as many as 48 transponders and offers up to 4,800 watts.

A more powerful version, the Boeing 601HP, made its debut in 1995. The Higher Power, or HP, versions can carry payloads twice as powerful as the classic Boeing 601 models and incorporate innovations such as gallium arsenide solar cells, and advanced battery technology. The 601HP features as many as 60 transponders and provides up to 10,000 watts of power.

The Boeing 601 satellite is a remarkably adaptable platform that can be configured with several types of antenna configurations that range from very simple reflectors systems to very complex, systems, such as the 15-foot diameter springback antenna aboard the NASA Tracking Data and Relay Satellite (TDRS) spacecraft. These steerable antennas can simultaneously transmit and receive in two different radio frequency bands, supporting dual independent two-way communication with the space shuttle, the International Space Station and dozens of unmanned scientific satellites in low earth orbit.

"The Boeing 601 satellite's biggest feature is its flexibility in support of multiple applications," said Art Rosales, Boeing 601 product manager for BSS. "For example, TDRS is a complex satellite with its large steerable antennas, which creates a very high demand on the control system to keep the spacecraft stable. Another example is the DIRECTV-4S spot beam antennas that enable local, customizable broadcasting. These antennas are fixed, but you have to have great pointing capability to keep the beams accurately pointed at all times."

Customers - past and present

The Boeing 601 satellite continues to shape the world's communications environment for customers. The following is a partial list of Boeing 601 satellite customers and how their satellites have made history:
