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.
