Increasing dependency on the global navigation satellite system (GNSS) constellations is raising concerns about what happens when signals are unavailable, even for short periods of time.
GNSS systems affect our daily lives in ways we often don’t see, from location services to cell phone timing. In fact, these satellites have become a necessary part of critical infrastructure, and higher accuracy is now making its way into mass-market applications. But increased dependency on GNSS also makes us vulnerable to any situation – intentional or not – if connections are interrupted…
Improvements to both signal structure and terrestrial equipment are helping to improve accuracy and redundancy. Recent developments have focused both on improving positioning accuracy and timing availability for wider consumer and industrial deployment.
