Complicated systems, like the ones created here at Mercury, beg for access to a management module that can monitor health and control the behavior of modules that make up these systems. These management modules can be separate, integrated on each module/board, or strictly software applications. Our SMP Engineering team has dealt with these many types and have incorporated them, depending on the customer’s application and the level of security that is required.
In my previous posts, I discussed the shortcomings and benefits of utilizing GPS as a primary Position Navigation and Timing (PNT) source. I also examined methods that provide Assured PNT (or A-PNT). These include hardening the GPS signal against jamming, while at the same time jamming the enemy’s receivers, utilizing encryption to provide spoofing immunity, and complementing GPS with other forms of PNT equipment.
This final post will focus on how complementing PNT systems can be combined together in a military vehicle and how this can be efficaciously integrated with other military ground vehicle systems.
