M-Code Benefits and AvailabilityThe Department of Defense (DoD) continues its work to field the GPS M-Code capability to improve the resistance of the Precise Positioning Service (PPS) to jamming and other emerging threats. As the DoD looks to employ this modernized capability as soon as possible, the United States Strategic Command, Air Force Space Command and the GPS Directorate have begun finalizing the military's plan for operational deployment of the M-Code system functionality. The USAF is on track to declare M-Code available in support of the congressional M-Code user equipment (UE) procurement mandate (Public law 111-383) and the integration and operational test of the military's first lead platforms to field M-Code beginning in fiscal year 2016. |
