摘要

The navigation payload for the Space Force’s forthcoming new GPS satellites has passed a critical developmental milestone, contractor L3Harris Technologies [LHX] announced Feb. 11. The company completed the critical design review (CDR) phase for the Space Force’s GPS Ⅲ Follow-On satellite’s payload, which will include a fully digital Mission Data Unit (MDU) for the first time, per a Feb. 11 release. The new MDU will provide more powerful signals and boosted capabilities over the L3Harris-made 70-percent-digital MDU in GPS III Space Vehicles 1 through 10.
