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.
Standard Features
- Patented Transcoder™
- Holdover options: Rugged OCXO (internal)
- RF GPS L1 output, compatible with existing coax antenna cable
- System meets PRTC-A ITU-T G.8272 spec
Enhanced Features
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
Resilient GEO/LEO Timing Services
VIAVI offers advanced and multi-orbit SecureTime Services, which can be combined to deliver defense-in-depth PNT capabilities.
ソフトウェアのダウンロードと更新
Secure µPNT-440 offer two SecureTime alternate timing services to maintain precise timing when GNSS signals are degraded, unavailable, or intentionally denied:
-
Alternate GEO Satellite Timing Services
Cost-effective satellite-based timing service using GEO satellites with global coverage. This option uses the altGNSS GEO-L service with an integrated receiver, delivering reliable timing through an outdoor antenna. Over-the-air subscription updates make it ideal for scalable, low-maintenance deployments.
-
Alternate LEO Satellite Timing Services
Satellite-based timing service using a global LEO constellation with service availability in enabled regions. This option uses the altGNSS LEO-STL service with an integrated receiver, supporting indoor and outdoor antennas. The higher signal power from LEO satellites provides jamming resistance and improved availability in indoor environments.
