Overview
Seismic applications involve monitoring and analyzing ground movements and vibrations, typically caused by seismic activity like earthquakes or volcanic eruptions. These applications benefit greatly from the reference clock that offers low power consumption, high precision, GPS synchronization, and holdover capability.
A reference clock with low power consumption ensures efficient energy usage, crucial for remote or battery-powered seismic monitoring stations. Devices like the Ocean Bottom Node are typically battery-powered and designed for long-term deployment, making low power consumption essential in such scenarios.
High precision ensures accurate timing and data collection, essential for precise seismic event detection and analysis.
GPS synchronization further enhances accuracy by synchronizing the clock reference with satellite-based time signals, providing precise timing information regardless of location. This feature ensures consistency and reliability in seismic data recording and analysis across different monitoring stations. GPS-disciplined function integrated oscillators are beneficial for land-based or downhole drill-type seismic applications, as they can simplify the design of the device.
Holdover capability is vital for maintaining accurate timing in the event of GPS signal loss or disruptions, ensuring uninterrupted operation and reliable data recording during adverse conditions such as signal interference or temporary GPS outages. This is especially important for the long-term deployment of underwater applications.
