US Military Invests in Next Generation GPS Capabilities

The US Space Force has canceled its troubled Next-Generation GPS Operational Control Segment (OCX) program and is instead moving forward with a new plan to upgrade its GPS ground system. The service has awarded Lockheed Martin a contract to work on the Architecture Evolution Program (AEP), which will support the launch and command and control of GPS IIIF satellites. However, the upgrade to operationalize the L5 signal, a key civilian signal, is still pending. The Space Force is working with the Department of Transportation and the Federal Aviation Administration to finalize a plan for the L5 upgrade, according to a report by Air & Space Forces Magazine.
