Tariq Mondal, Jeffrey Sherman, David Howe
The Global Positioning System (GPS) is the most prevalent Global Navigation Satellite System (GNSS) that provides Position, Navigation, and Timing (PNT). GNSS vulnerability is well-known, and the search continues to find another independent system that can

Evaluation of L5 Band GNSS for Use in Time-Transfer

January 27, 2025
Author(s)
Benjamin Pera, Andrew Novick
The L5 frequency band of GPS features a higher power, higher code rate, and superior performance in GNSS denied or degraded environments. GPS L5 is pre-operational at time of writing with 17 satellites but has sufficient coverage for testing and utilizing
