The Secure µPNT‑440 protects mission‑critical systems from GPS jamming and spoofing by generating a clean GPS L1 signal from trusted alternative sources. Using VIAVI’s Transcoder technology, it seamlessly converts authenticated multi‑constellation GNSS, GEO SecureTime corrections, or LEO STL signals into a reliable GPS output, allowing legacy GPS‑dependent clocks to function normally even during outages or attacks. With precision holdover, UTC‑traceable accuracy, and TrustedPNT source selection, it delivers resilient, continuous timing for defense, communications, infrastructure, and other critical applications.
