Long-term tests of 6D7 real time clock reveal exceptional accuracy
Precise and accurate timing information is paramount to seismological data. However, providing a stable time-base for periods of 12 months or longer in autonomous ocean bottom instruments is challenging. In 2023 K.U.M. launched a new ocean bottom seismic data logger, the 6D7. Building on K.U.M.’s vast experience in OBS technology, we started from scratch in developing a new seismic data logger that meets the highest standards in power efficiency, energy consumption, reliability, and real-time clock performance over extended time periods.
The 6D7 is equipped with a new real-time clock that promises extremely accurate timing of seismic data. To verify these claims K.U.M. has conducted multiple tests during the development process. In this report we present the analysis results of two lab tests assessing the performance and stability of the real-time clock implemented in the 6D7 data logger.
