Navigating the Impossible

Northrop Grumman is a proven leader in engineering powerful and resilient assured positioning navigation and timing (A-PNT) solutions that guide warfighters through the most challenging environments. Our cutting-edge navigation systems maximize survivability and ensure mission success, even when GPS signals are compromised or unavailable. At Northrop Grumman, we’re defining what’s possible with navigation technology each day.

Positioning Systems Overcoming Any Challenge

Northrop Grumman’s approach moves the burden of trusted A-PNT Hub away from sole reliance on GPS to the complementary use of inertial devices augmented with additional alternative methods of navigation. Inertial Navigation Systems calculate direction moved over time, with a varying degree of drift, and with the use of high precision oscillators provide continuity of time. The Inertial Navigation Systems' great advantage is that they cannot be spoofed or jammed.
