Fully automatic four-channel submarine seismic system

OBN's new ocean floor seismic node technology outperforms conventional seismic data acquisition methods. Each node requires no cable and is tightly coupled to the seabed, providing good seismic data acquisition capabilities in extremely crowded and open waters.

Compact structure

A compact submarine seismic node acquisition system consisting of hydrophone, three-component seismic sensor and data acquisition system. The rechargeable battery can guarantee continuous operation of the entire system for up to 30 days. The station has WiFi connection function, which supports users to remote control and parameter setting of OBN before entering the water.

Advanced electrochemical sensor

OBN seismometer and hydrophone adopt advanced electrochemical sensor technology, with high dynamic range, low self-noise and low power consumption characteristics, especially suitable for coastal ecotone and shallow water area seismic research and investigation, the maximum working water depth of 500 meters. Its biggest advantage is that the support equipment can work in a variety of orientations, without additional leveling structure and orientation operations.

Multiple communication modes

OBN offers two possible ways to connect to a PC: wireless (WiFi) or wired (USB) connection. Both of these methods allow you to set commands and parameters to view the sensor's signal and system status. Data from the SD card can be downloaded via a USB cable connection using the high-speed card reader mode.
