Rugged buoy up to sea state 5

Rubhy is a moored acoustic buoy useful for scientists doing real-time marine assessment and offshore companies looking for pile-driving mitigation. Additional sensors could also be added.


Rubhy bandwidth can go up to 500kHz at 1250 kS/S while batteries can last 40 days non-stop.

Memory goes up to 4TB on HDD.

Following options are available: Wifi, VHF, 4G, Iridium, Cable to the shore (up to 1.5km), GPS, Temperature, Pressure, RS232 serial port, and low-frequency module.

Communication and data

Data logger description

The buoy streams the Sound Pressure Level (SPL), the Sound Exposure Level (SEL) and the 1/3rd octave band spectrum, every 5 seconds to the dedicated software.

Web based control and tracking


UHF/VHF communication


Other sensors or additional information

The web interface embedded in the RB-SDA14 system is accessed at all time with a remote control. The manager software of an additional tool that allows for more real-time functions: - buoy(s) access - synchronous time set- multiple buoys synchronization - recording status control - .wav data sample collection while recording
