Differential Signals-of-Opportunity Timing Back-Up Method on VHF Band for Critical Infrastructures

Differential Signals-of-Opportunity Timing Back-Up Method on VHF Band for Critical Infrastructures

This paper describes a back-up method for GNSS-free timing for power lines which is currently achieved using fibre links. The method is based on software-defined-radio technologies for monitoring low-frequency signals of opportunity (SoOp) serving as an alternative timing signal. Our solution utiliz...
