The Challenge
Beyond GPS
Reliable navigation and synchronization require more than a satellite signal.
Through its subsidiary, FEI-Zyfer, FEI designs and manufactures advanced PNT and 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.
Architecture
Resilient Timing and Navigation
FEI supports modern A-PNT architectures through the integration of
- GPS and GNSS timing systems
- Atomic frequency standards
- Precision oscillators
- Timing distribution systems
- Multi-source synchronization architectures
- Holdover timing technologies
These technologies enable systems to maintain synchronization and operational continuity during signal disruption, contested operations, or degraded navigation conditions.
