Summary:

DOD has been developing the capability to use its more jam-resistant military-specific GPS signal for 2 decades. The Air Force launched the first GPS satellite capable of broadcasting the M-code signal in 2005, but is only now completing development of the software and other equipment needed to use it. The GPS modernization effort spans DOD and the military services, but an Air Force program office is developing M-code cards for eventual production and integration into weapon systems. This report discusses DOD's progress and challenges (1) developing M-code receiver cards, and (2) developing receivers and taking other steps to make M-code-capable receivers available for fielding.

Contents:

Background
