Marine Surveillance

NiKA, developed by MetOcean Telematics, revolutionizes underwater acoustic data collection and transmission. Its advanced hydrophone assembly allows it to gather precise acoustic data at depths of up to 1000 meters. It provides real-time acoustic detection and satellite localization of submarines, making it indispensable for naval operations.

Marine Noise

NiKA silently listens to the ocean to detect subsurface assets, protecting assets and harbours. It captures acoustics data at various depths, storing data that stands out versus ambient noise. At the surface, collected acoustic and positional data is transmitted by NiKA over the Iridium Certus® service, providing pole-to-pole satellite coverage.

NiKA is a state-of-the-art autonomous maritime surveillance platform that combines advanced technology with exceptional performance. Equipped with a custom hydrophone assembly, NiKA efficiently gathers precise acoustic data by cycling through the water column before surfacing to relay the collected data. This critical information, along with the platform’s real-time position, is then transmitted using the highly reliable Iridium Certus® 100 mid-band satellite service.

The device is capable of operating at depths of up to 1000 meters, making it a versatile and flexible complement to traditional sonobuoys, fixed and towed arrays. NiKA’s exceptional operating life of over a year makes it the ideal solution for long-term monitoring, anti-submarine warfare surveillance, and underwater ocean profiling. It provides critical command and control capabilities for naval operations, delivering real-time acoustic detection and satellite localization of submarines.

Whether for military or commercial purposes, NiKA offers a cost-effective and indispensable tool for safeguarding against underwater threats.
