Harris Builds Antenna Reflector for TerreStar Satellite (9/28/09)
An 18-meter antenna reflector built by Harris for the geosynchronous TerreStar global communications satellite was successfully deployed on orbit July 12. The large size of the reflector, compared with 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, a Harris statement said.
Harris provided the reflector and the onboard articulating boom to Space Systems/Loral, which designed and built the TerreStar-1 satellite for TerreStar Networks. 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 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 to provide mobile satellite services (MSS). The S-band antenna and payload are part of a hybrid infrastructure that combines an all-IP satellite and smart-phone technology with terrestrial networks.
