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 that is compatible with Ocean Sonics icListen digital hydrophones.
Paired with an OceanSonics icListen digital hydrophone, the gListen Board keeps track of events detected by this hydrophone and relays this data. The board facilitates near real-time event detection and spectrum retrieval. User-configured frequency spectra can also be transmitted.
It is an intelligent peripheral for the marine sensor market that benefits the environmental monitoring service value chain. This product reduces development and operational costs for a number of stakeholders – from marine platform and hydrophone manufacturers to end users for various applications.
End users of the gListen Board are maritime and port security stakeholders, offshore oil, gas and wind operators, academic researchers and government organizations that need to gather information offshore but do not have the resources available for bespoke engineering.
Integration with Bristlemouth Development Kit
The gListen Board was initially developed to conduct Passive Acoustic Monitoring (PAM) with ocean gliders. For other oceanographic platforms, the gListen Board can be paired with a Bristlemouth Development Kit.
