Flight Demonstration System (FDS)

Part of the SBIRS Low Program Definition and Risk Reduction (PDRR) program phase. The FDS will consist of two satellites and a ground system being built by TRW/Hughes. The FDS satellites are to be launched in FY99 for a two-year test program to demonstrate operations and performance of a SBIRS Low concept, collect target and phenomenology data to support the objective system design, and validate cost estimating models.
