The satellite gurus over at Air Force Space Command are making progress on modernizing the equipment, ground control systems, and military-user tools needed to upgrade the Global Positioning System. According to a Wednesday release from AFSPC, eight of the latest Block IIR replenishment satellites will be modernized with new military codes and a civil signal, and the first GPS IIR-M is scheduled for launch later this year. The new signals will provide less vulnerability to interference and increased performance in accuracy, availability, integrity and reliability.
The Space Development Agency says it’s on track to issue its next batch of missile warning and tracking satellite contracts this month after those awards were delayed by the Pentagon’s decision to divert funds from the agency to pay troops during this fall’s prolonged government shutdown.
