Military PNT — The Way Ahead

Changing the Game Changer

GPS-based positioning, navigation, and timing (PNT) have profoundly changed how the U.S. Defense Department carries out command and control in the electronic battlespace — from a reactive to a real-time mode of continuous situational awareness. Now military leaders are looking for the technologies that can fill the gaps in PNT that occur in GPS signal–challenged conditions.

Local Oscillator Phase Noise

Effects on GNSS Code Tracking

When GNSS designers quantifiy the performance loss due to phase noise effects on the baseband signal, these performance bounds may then be used as the basis for local oscillator design. The authors develop bounds by identifying front-end local oscillator phase noise effects on the correlation loss, while tracking receiver performance. This is one of the first articles to characterize and document the effects.
