TRW-Built NRO GeoLITE Satellite

18 May 2001


The National Reconnaissance Office's (NRO) Geosynchronous Lightweight Technology Experiment (GeoLITE) satellite, built by TRW, is slated for launch on May 17 on a Boeing Delta-II launch vehicle at Cape Canaveral Air Force Station.

GeoLITE, an advanced technology demonstration satellite, is the first mission for TRW's T-310 satellite bus, a new lightweight, highly stable platform capable of a range of missions. TRW has system integration responsibility for GeoLITE, including the satellite development, integration and preparation for launch. The satellite was designed and built in 3 1/2 years using streamlined program methodologies.

TRW's T-310 modular bus design provides flexible capability for a variety of applications, including geostationary communications and weather observation missions, as well as planetary missions. The design features common subsystems scalable to the mission-specific needs. Instrument payloads can be attached on a ""mix and match"" basis without changes in the overall design or subsystem support requirements. Weighing less than 1,500 pounds and equipped with 1.2 kilowatts (end-of-life) of electric power, the T-310 bus for GeoLITE is built of lightweight composite materials that allow for increased instrument weight and reduced launch costs.
