Boeing — TDRS Review Is Righteous

Boeing [NYSE: BA] and its customer NASA have announced that the Tracking and Data Relay Satellite (TDRS) K-L program successfully completed its system-level Critical Design Review (CDR) and Production Readiness Review (PRR) in El Segundo on February 19. When TDRS satellites K and L join the operational TDRS constellation on orbit, they will provide voice, data and communications relay services to Earth-orbiting spacecraft, such as the International Space Station, several launch vehicles and the Hubble Space Telescope.

The CDR and PRR bridge the design and manufacturing stages of the TDRS program. The reviews validate that the TDRS K-L system design will meet NASA’s requirements, is backed with solid analysis and documentation, and will operate effectively when the satellites launch in 2012 and 2013. Based upon this successful review, Boeing will begin assembly of the K and L satellites. Both reviews were presented to an independent board that evaluated the design aspects of TDRS K and L, including spacecraft assembly and systems integration, testing and safety requirements. TDRS K and L are the 11th and 12th satellites to be built for the TDRS system. Together with the Boeing-built TDRS 8, 9 and 10, which launched in 2000 and 2002, TDRS K and L will help to replenish the aging TDRS constellation, which was established in 1983 to replace NASA’s worldwide network of ground tracking stations.
