Global Navigation Satellite Systems Engineering, Policy, and Design
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.
