Advanced concept for chip-scale atomic clocks

Interest in compact and low power consumption atomic clocks (aka CSAC, Chip-Scale Atomic Clocks) have been progressively increasing in the last decade based on benefits demonstrated for a wide range of application, such as PNT in adverse environment (long coherent integration), secure telecommunication (frequency hopping) or in order to allow timing hold-over capability in case of loss of GNSS…

PNT Timing & Synchronisation for Aviation Systems and Networks

GNSS is extensively used in aviation, notably for: positioning and timing for on board navigation purposes; timing and synchronisation for datalink communications (board to ground and viceversa); timing and synchronisation on ground for Surveillance, Air Traffic Control (ATC) and communication networks. GNSS time outages or unexpected anomalies may affect aviation systems and…
