M-Code Acquisition via Extended Integration under Jamming (MAXIUM)

QuNav, LLC (Fort Walton Beach, FL) and its subcontractor, Northrop Grumman Mission Systems (NGMS, Woodland Hills, CA), are pleased to propose prototyping of the M-code Acquisition via eXtended Integration Under jaMming (MAXIUM) technology, whose feasibility was demonstrated in Phase I through extensive computer simulation. In Phase II, a real-time embedded bread-board prototype of MAXIUM will be developed and validated under severe jamming conditions. When operating in a standalone mode with a single antenna, MAXIUM burns through strong jamming by building up the desired M-code signals while averaging out noise and jamming. MAXIUM introduces two key technological improvements to the state-of-the-art direct acquisition of M-code, namely, (i) long coherent integration of received signals and (ii) multi-frequency signal accumulation. Phase I simulation results demonstrate that the above technological enhancements enable MAXIUM to acquire M-code signal under 51 dB jamming-to-signal power ratio and over 10 ms of timing uncertainty. In Phase II, MAXIUM will be prototyped and demonstrated on the NGMS embedded MAGNOM card. MAGNOM is form-factor compatible with Embedded GPS/Inertial (EGI) products such as LN-260. This will enable insertion of MAXIUM into EGI products via a firmware upgrade, thus establishing a clear path for technology transitioning.
