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 space-based PNT RF signals.

Spirent Federal Systems
To provide background for the topic, Jennifer Smith, Director, Business Development, at Spirent Federal Systems, will summarize government directives that address GPS vulnerabilities.

Northrop Grumman
Naveen Joshi, Director, BD & Strategy, Navigation & Cockpit Systems, at Northrop Grumman Mission Systems, will analyze inertial navigation’s role in Assured PNT and GPS augmentation.

• History of inertial navigation technology
• Emerging trends in inertial navigation: focus on recent enhancements in fiber-optic gyro (FOG) technology
• Future of navigation: case study on Northrop Grumman’s approach to Embedded Global Positioning System (GPS) / Inertial Navigation System (INS)-Modernization, or EGI-M

Spirent Communications
Mark Holbrow, Senior Director, R&D Positioning Technology, at Spirent Communications, will discuss coherent GNSS and inertial sensor emulation, plus the opportunity for exploring and simulating emerging alternative space-based PNT RF signals.

• Fundamentals of inertial emulation, real world sensor modeling, and a review of supported IMU/EGI variants
• Opportunities to explore, experiment, and test with simulated RF and baseband signals to support both evolving GNSS needs and emerging complementary space-based alternatives

Spirent Federal Systems
Roger Hart, Director, Engineering, at Spirent Federal Systems, will examine existing GNSS/inertial and alternative RF navigation capabilities, plus imminent product developments.
