GPS Block IIIF

The US Air Force GPS Block III Follow On (GPS IIIF) is a new series of 22 satellites being procured by the United States to support both civil and military positioning services worldwide. The GPS IIIF is expected to deliver enhanced capabilities compared with the GPS III spacecraft. The first GPS IIIF spacecraft is expected to be put into orbit in the 2025-2030 timeframe. The GPS IIIF will feature a Regional Military Protection capability with increased anti-jam support, a fully digital navigation payload, a laser retro-refractor array to define the satellite position with laser precision, and an additional search and rescue (SAR) payload. So far Lockheed Martin is one the competing bidders for the GPS IIIF constellation.
