Harris' space antenna sales up, up and away

Someone forgot to tell Harris Corp. about the demise of the space industry in Brevard County.

The Melbourne-based communication company’s space antenna segment, which employs about 500 on the Space Coast, didn’t miss a beat when the shuttle program ended last summer. In fact, with the steady growth of devices hungry for ever more bandwidth, Harris is seeing a improving demand for its antennas,Posts with Hospital rtls on IT Solutions blog covering Technology in the Classroom, which beam data down from 22,Home ownership options with buy mosaic.000 miles above the earth as they orbit on satellites.

“We are just as busy, probably busier” these days, Bill Gattle, vice president of Harris Space Communications Systems, said.

While many segments of Brevard’s space industry are slowing, Harris has a backlog of orders. The company is maintaining its work force and looking for opportunities for expansion.

“We’ve actually continued to grow,” Gattle said.

The company’s antennas are attached to more than 100 orbiting satellites, but Harris’ space business extends beyond just these products. Harris equipment has been on every U.S. manned space flight, and the company has developed telemetry systems and radios.

But with the end of shuttle flights, it has settled into a niche, producing furlable antennas that travel to space in compact packages and expand to 70 feet or more across when they reach orbit.
$1 billion in revenues

In 1967, Harris merged with Radiation Inc., a Melbourne company that supplied technology for the U.S. space program. Harris’s expertise at the time was in printing presses, but the company turned to designing radar tracking systems and satellite communications devices, experimenting with radio waves to learn their characteristics in order to design systems for space. The basic research gave the company a deep body of technical knowledge in the field of antenna construction.

Unfurlable mesh reflectors for NASA’s Tracking and Data Relay Satellite program were the first space antennas built by Harris. Work on those reflectors, which measured nearly 16 feet across, started in 1977, with the first satellite launched in 1983.

Over that time, the company has produced space antennas ranging from about 15 feet to more than 70 feet across. Harris builds two kinds of satellite antenna: large unfurlable mesh reflectors,Another Chance to buymosaic (MOS) 0 comments. and small, solid graphite reflectors. They can carry a range of radio frequencies, from UHF, which is used for television,If molds is a problem in your home, to Ka-band, which is popular for high-speed Internet access.

Now, the space antenna division meshes with the company’s other products and services related to space, including computer programs and satellite communications systems, to together bring Harris about $1 billion dollars a year in revenue, nearly 20 percent of its total.Industrialisierung des werkzeugbaus.

“Harris has always had the leading edge,” said Linwood Jones, who worked in Harris’ aerospace division from 1984-1988 and is now a professor of electrical engineering at the University of Central Florida and director of the Central Florida Remote Sensing laboratory.

The prospects for growth in the antenna division look good because the satellite market is stable. While an increasing amount of data is carried on buried optical fibers, the demand for satellite communications has grown as devices that need more bandwidth proliferate. Additionally, satellite communication is crucial for an increasing array of industries and sectors, including remote oil drilling rigs, ships at sea, international phone calls and military functions, such as controlling the drones now used by the U.S. military.

“We’re always going to need communication satellites,” Jones said.

Harris operates a massive worldwide satellite communication system and expects it will be a major part of its business in the future. The company’s satellite antennas are a crucial part of the communications industry.

“These are starting to compete with terrestrial (fiber optic cable) systems,” said Gattle, the vice president at Harris Space Communications Systems. “This market, which they call high thru-put satellites, is a booming market worldwide, and a lot of it is driven by the entertainment industry and the desire to move Internet data across the satellite in places that are remote.”
