Assured Positioning, Navigation and Timing (PNT)

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.

A range of sensors can contribute to the provision of Assured PNT, with their data fused using an open architecture, open interfaces and modular software.
