Global Navigation Satellite Systems Engineering, Policy, and Design
In recent years, the threat of spoofing — the transmission of false signals intended to deceive satellite navigation receivers — has become increasingly prominent.

Critical National Infrastructure (CNI) is vulnerable to loss of GNSS for positioning, navigation, and timing (PNT). Low Frequency (LF) systems like eLoran offer a robust alternative, especially where satellite signals are degraded or unavailable. Strong 100 kHz eLoran signals are resilient to space weather and difficult to jam or spoof.

The APNT problem statement and notional requirements for UAVs and Loitering Munitions.
By Inside GNSS
In today’s contested battlespace, positioning, navigation and timing (PNT) solutions must withstand jamming, spoofing and degraded visual conditions. For Loitering Munitions and unmanned aerial vehicles (UAVs), precision absolute PNT is mission-critical—not just ideal.

As GNSS denial becomes a baseline condition across military and civilian operations, VIAVI Solutions is building a modular, multi-layered PNT ecosystem that integrates precision timing, inertial navigation and signal intelligence. With strategic acquisitions and field-proven technology, VIAVI is redefining resilience at the edge—where assurance is not optional, and adaptability is mission-critical.
