GPS III

The GPS III constellation is the latest block of U.S. positioning, navigation, and timing satellites. Each GPS III space vehicle delivers three times better accuracy and eight times improved anti-jamming performance over GPS IIF, and adds the new L1C civil signal interoperable with Galileo.

GPS IIIF, the follow-on block now in production, adds Regional Military Protection, a search-and-rescue payload, and an accuracy-improvement laser retro-reflector. GPS III/IIIF maintains U.S. leadership in global PNT services as one of the most widely used space capabilities on earth.
