The Department of Defense (DoD) has a need to maintain Positioning Navigation and Timing (PNT) dominance against an evolving PNT threat. The Resilient-Embedded Global Positioning System (GPS) /Inertial Navigation System (INS) (R-EGI) design effort is developing a solution that will meet this need for airborne platforms. In R-EGI, a resilient solution is defined by the following three attributes:
• Avoiding the threat through the use of alternative-PNT (alt-PNT) and improved GPS/Global Navigation Satellite System (GNSS) Signal processing with technologies such as GPS Software Defined Radio
• Recovering from a new threat by rapid development and validation of capabilities, and
• Reconstitution of this capability through affordable integration into weapon systems.
There are many challenges to achieving these goals for airborne platforms including:
* insertion of capability while managing:
** airworthiness (both military & civilian,)
** cyber / authority to operate,
** and configuration management,
* appropriate ownership of intellectual property to enable resilience,
* balancing legacy vs. future needs (vs. requirements),
* operationally validating alternative PNT for specific missions,
* moving at the speed of relevance,
* and the acquisition approaches for the above.
This presentation will discuss the various approaches R-EGI is taking to overcome these challenges including but not limited to key architectural decisions (MOSA concepts), platform engineering work, and the acquisition approach.
