The gListen Board is an Ethernet to RS-232 converter with voltage regulation and onboard memory for reading and extracting data. It is an innovative marine autonomous system (MAS) accessory compatible with Ocean Sonics icListen digital hydrophones.
Paired with an OceanSonics icListen digital hydrophone, the gListen Board keeps track of events detected by the hydrophone and relays this data, facilitating near real-time event detection and spectrum retrieval, with user-configured frequency spectra also transmittable.
It is an intelligent peripheral for the marine sensor market that reduces development and operational costs for stakeholders — from marine platform and hydrophone manufacturers to end users. End users of the gListen Board include maritime and port security stakeholders, offshore oil, gas and wind operators, academic researchers, and government organisations that need to gather information offshore but do not have the resources for bespoke engineering.
The gListen Board was initially developed for Passive Acoustic Monitoring (PAM) with ocean gliders; for other oceanographic platforms, it can be paired with a Bristlemouth Development Kit.
