Positioning, Navigation, & Timing
Numerica develops robust, distributed, and scalable algorithms that provide localization and clock synchronization capabilities to platforms in GPS-denied environments.
Numerica develops robust, distributed, and scalable algorithms that provide localization and clock synchronization capabilities to platforms in GPS-denied environments.
Positioning, Navigation, and Timing (PNT) is a critical capability to the United States military, government services, and commercial sector. The growing prevalence of inexpensive and easily available GPS-jamming technology requires resilient navigation and timing independent of GPS.
Numerica provides advanced solutions for restoring PNT to a network of agents in the absence of reliable GPS measurements. Our technology
provides hyper-accurate time-of-arrival estimation to provide ranging, timing, and distributed localization. Our solution is scalable to networks of thousands of interconnected platforms, and is robust to dynamic network configurations.
