Secure microPNT-440 Module

The µPNT-440 offers an affordable way to upgrade legacy GPS/GNSS clocks, enabling secure, resilient, and modern PNT capability.

Aging GPS/GNSS systems, delays in modernization, the growing reliance on GPS, and increasing GPS/GNSS vulnerabilities from jamming and hacking - all emphasize the need to consider the benefits of upgrading to newer technologies.

VIAVI's Secure µPNT™-440 Module is a next generation resilient timing solution that is powered by our innovative TrustedPNT™ technology and an intelligent zero-trust multi-source platform.

The µPNT-440 module is an affordable in-line solution that can be used to quickly update legacy GPS/GNSS systems to be more secure, resilient systems that are capable of supporting modern technologies.

Features:

• Patented Transcoder™
• Holdover options: Rugged OCXO (internal)
• RF GPS L1 output, compatible with existing coax antenna cable

The µPNT-440 is a GPS/GNSS receiver that supports VIAVI's new SecureTimeSM GEO and LEO Services. When used in combination with the SecureTime Services, the µPNT-440 module provides the following enhanced features:

eGNSS GEO: Provides enhanced spoof detection and mitigation with <2.5 ns RMS accuracy to UTC

altGNSS LEO-S: Iridium GNSS-independent reference with <65 ns RMS accuracy traceable to UTC
