A time synchronization method of multi-source data for ocean-based observation platform

Abstract

In this paper, a time synchronization method of multi-source data of ocean-based observation platform is proposed, which realizes the fusion of multi-source sensor data of ocean-based observation platform in time dimension. In this method, a timer is used to generate a high resolution local clock system which operates independently. Combined with the universal time and pulse-per-second signal generated by the GNSS receiver, the local clock system and universal time are synchronized to output a stable, reliable, sustainable and high resolution sensor time. This method has been applied in the sea trial and achieved good results.
