Hughes installing hybrid VSAT network for Chevron.

Hughes Network Systems (HNS) Inc. has begun installing a massive $40 million telecommunications network for Chevron Corp. The contract is noteworthy not only for its size--approximately 4000 remote terminals will be installed--but also because it represents the first deployment of a new very-small-aperture-terminal (VSAT) product from Hughes. The Personal Earth Station 6000 (PES 6000) uses a smaller antenna than do competitive offerings, and this represents the state of the art in VSAT technology.

The landmark Chevron network includes the installation of a hub in San Ramon, Calif., a backup hub in Houston, and the commissioning of the miniaturized three-quarter-meter terminals at Chevron locations.

The PES 6000s will carry Chevron's RAN (Retail Automation Network), which is used for point-of-sale (POS) applications such as credit-card authorization at high-volume service stations.

Many Chevron corporate sites running standard financial and administrative applications will employ Hughes' PES 8000 product with a 1-meter antenna that can accommodate higher levels of inter-active data traffic. Video broadcasting will also be available to these sites.

The VSAT RAN network replaces a terrestrial 2400 b/s multidrop leased-line configuration, which accessed Chevron's packet-switched network. The new network will provide a maximum response time of two seconds. With its low-profile three-quarter-meter antenna, the PES 6000 product offers Chevron economic, technological, and aesthetic advantages over transmission alternatives.

"Telecommunications plays an important role in helping run Chevron's business efficiently," says Bill Houghton, president of Chevron Information Technology Co. "We expect that this new technology will allow us to improve network availability and quality of service while significantly reducing costs."

Note Jack Shaw, HNS chairman: "We are pleased to offer Chevron the advantages of the newly expanded PES family. The latest breakthroughs in VSAT technology have resulted in an economical yet powerful range of antennas that keep a low profile in retail applications. The Chevron contract thus represents not only one of the largest satellite networks in the world but one of the most advanced."

Chevron Corp., based in San Francisco, is the nation's largest refiner and marketer of petroleum products.

Hughes Network Systems Inc. is a world leader in advanced digital telecommunications. A premier provider of interactive VSATs, HNS offers communications network solutions that include the Personal Earth Station series, the Gemini earth station, Telephony Eart Station, and in InTELEconference videoconferencing system. In addition, HNS features the SkyRider mobile satellite communications system and the Intergrated Packet Network turnkey packet-switching product line. Headquartered near Washington D.C., HNS is a subsidiary of Hughes Aircraft Co., a unit of GM Hughes Electronics.
