GPS Vulnerability Mitigation: Using Inertial & Complementary PNT

While GPS will always be an integral and irreplaceable part of PNT, Assured PNT must take a layered approach due to GNSS vulnerabilities. Join Spirent and Northrop Grumman as we examine the future of inertial navigation in Assured PNT and GPS augmentation, EGI-Modernization, coherent GNSS and inertial sensor emulation, and exploring and simulating emerging alternative […]

Transportation Requires a Fusion; Now to Test It

Inertial navigation systems (INS), like most navigation systems, have evolved through countless iterations and improvements over many years. An INS, unlike other navigation technologies, does not rely on any external signals or inputs to aid navigation. It is, therefore, extremely difficult to spoof, jam or disrupt the system, and solar flares, ground/sky visibility and climate […]
