Successful satellite antenna reflector deployment

Harris Corporation : 10 March, 2014  (Application Story)
The Antenna reflectors on Sirius FM-6 Satellite have been successfully deployed in the latest mission success
Successful satellite antenna reflector deployment

An advanced antenna reflector designed and built by Harris Corporation has been successfully deployed in space onboard the Sirius FM-6 satellite which was designed and built by Space Systems/Loral (SSL) for SiriusXM.

The high-performance reflector has a 9-meter diameter aperture when fully deployed and delivers a high-power signal to support the delivery of commercial-free music; premier sports talk and live events; comedy; news; exclusive talk and entertainment; and the most comprehensive Latin music; sports and talk programming in radio, to SiriusXM’s 25.6 million subscribers.

The reflector features a Harris-patented, gold-plated mesh reflective surface, coupled with a unique design that maximizes antenna gain and provides the improved performance required for mobile media services while reducing stowed volume and antenna mass.

During launch, the Harris reflector was stowed onboard the Sirius FM-6 satellite much like an umbrella. Once on orbit, SSL controllers executed a series of maneuvers, and sent the commands to deploy an articulating boom and then unfurl the reflector. The reflector and boom were manufactured at Harris facilities in Palm Bay, Florida.

"This continues our successful track record of working with SSL and is the fourth flawless deployment of Harris reflectors for SiriusXM,” said Bill Gattle, vice president and general manager, National Programs, Harris Government Communications Systems. “The Harris reflectors help SiriusXM provide its subscribers with the best audio entertainment experience possible.”

SSL designed the Sirius FM-6 satellite to help ensure SiriusXM’s array of audio and data services are received by vehicles, receivers for home and business, as well as mobile devices, and will play an important role in bolstering the continuity of service for years to come.

With more than 50 reflectors in orbit, Harris is the leading supplier of large reflector apertures and deployable mesh reflector-feed antenna systems for all orbital regimes, from UHF-Band through K-Band. Harris reflector products have the highest surface accuracy design in the industry, while substantially exceeding the specified mean mission duration of the spacecraft and payload.
