Largest Reflector Ever Launched for Commercial Application Will Bring Satellite Communications Directly to Mobile Users in North America MELBOURNE, Fla., Sept. 28 /PRNewswire-FirstCall/ -- An 18-meter antenna reflector built by Harris Corporation (NYSE:HRS) for the geosynchronous TerreStar (NASDAQ:TSTR) global communications satellite was successfully deployed on orbit on July 12, 2009. The large size of the reflector, compared to more traditional 9- or 12-meter designs, will help to ensure broad coverage and 24/7 delivery of mobile voice, data and video services directly to mobile devices and vehicles in the continental U.S. and Canada, as well as Alaska, Hawaii and Puerto Rico. Harris, an international communications and information technology company, provided the reflector and the onboard articulating boom to Space Systems/Loral, which designed and built the TerreStar-1 satellite for TerreStar Networks Inc. The Harris reflector features a unique design that allows it to be stowed in a smaller space, while still providing increased antenna gain and the improved performance levels required for mobile, interactive media services. The TerreStar-1 satellite features an innovative, S-band payload that enables delivery of two-way mobile voice, data and video services directly to conventionally sized mobile terminals. The Harris antenna reflector makes it possible for the TerreStar-1 satellite to focus the 2 GHz S-band signals on the United States and Canada in order to provide these Mobile Satellite Services (MSS). The S-band antenna and payload are part of a hybrid infrastructure that combines an all-IP satellite and smartphone technology with terrestrial networks. The reflector features a gold-plated mesh reflective surface and a unique design that maximizes antenna gain while reducing stowed volume and antenna mass. During the satellite's launch by Arianespace from French Guiana on July 1, the Harris reflector was stowed onboard much like an umbrella. Once on orbit, Space Systems/Loral controllers executed a series of maneuvers, and sent the commands to deploy the articulating boom and then unfurl the reflector. On orbit tests have confirmed that the reflector is fully deployed in its intended position. Harris has over 30 years of heritage designing, building and flying deployable mesh reflectors for government and commercial applications. With over 40 reflectors in orbit, Harris is the dominant supplier of large reflector apertures and deployable mesh reflector-feed antenna systems, from L-Band through K-Band, for all orbital regimes. Harris reflector products have the highest surface accuracy and most mass efficient design in the industry, while substantially exceeding the specified mean mission duration of the spacecraft and payload. "The successful deployment of this large reflector enables TerreStar to deliver today's most advanced communications services over a very large area using a single satellite instead of the constellation of satellites required in the past," said Dan Pearson, group president, Harris Government Communications Systems. "The antenna is meeting or exceeding all established performance metrics. This successful deployment will usher in a new era of mobile multimedia services and smartphone communications for U.S. and Canadian consumers. We are very pleased to be part of the Loral/TerreStar team in delivering these next-generation satellite services."
