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.
