GPS alone is no longer sufficient for mission-critical operations.

Modern military, aerospace, and critical infrastructure systems depend on accurate positioning, reliable navigation, and precise timing to operate effectively. However, today's operational environments increasingly require resilient solutions capable of maintaining performance when GPS signals are unavailable, degraded, jammed, or spoofed.

Through its FEI-Zyfer subsidiary, FEI designs and manufactures advanced PNT and Assured Positioning, Navigation and Timing (A-PNT) systems that combine GPS and GNSS technologies with atomic clocks, precision oscillators, timing references, and resilient synchronization architectures. These systems enable platforms and networks to maintain accurate timing and positioning information even when external signals become unreliable or unavailable.

Key Applications

Supporting mission-critical operations across demanding environments.

Contested & Autonomous Operations

GPS-denied and contested operations; autonomous air, land, sea, and undersea platforms; and missile and hypersonic guidance systems.

ISR, EW & Secure Networks

Intelligence, Surveillance, and Reconnaissance (ISR); electronic warfare (EW); C5ISR systems; and secure communications networks.

Space & Critical Infrastructure

Space-based navigation and timing; distributed satellite constellations; and critical infrastructure synchronization.

Core Capabilities

Beyond GPS — resilient timing through FEI-Zyfer.

FEI supports modern A-PNT architectures through integration of GPS and GNSS timing, atomic clocks, rubidium frequency standards, precision oscillators, and multi-source synchronization architectures. These technologies enable systems to maintain synchronization and operational continuity during signal disruption, contested operations, or degraded navigation conditions. As defense organizations and critical infrastructure operators seek greater resilience against jamming, spoofing, and signal denial, Assured PNT has become a strategic priority.
