Bad clocks, Brexit and what’s happening at the European Space Policy Conference

It just wouldn’t seem like a Galileo New Year without a setback to report, but guess what, no setbacks to report. So, for anyone expecting rancor and excuse-making, the Annual Conference on European Space Policy in January was a bit of a let-down.

GNSS & the Law

Traceable Time from GNSS Signals

Precise time is crucial to a great variety of economic activities around the world. Here, the authors will show how the time obtained from GNSS satellite signals is related to the international time scale, UTC, and explain how GNSS receivers can be used to ensure that they are operating correctly, as reliable and traceable sources of time.

Codeless Code Tracking

of the Galileo E1 PRS

Code/subcarrier divergence in high order BOC signals is investigated on the Galileo E1 PRS signal. The authors introduce “codeless code tracking” as a potential means for future quality monitoring or as the basis for a high-accuracy PRS-based anti-spoofing mechanism.
