TR-ORCA

Underwater Acoustic Data Acquisition Product Family
Rich, broadband, underwater acoustic recording and signal processing.

Now you can capture, record and process, in real time, extremely rich underwater acoustic data sets. The TR-ORCA product family is available in full size and mini versions, both supporting five synchronously sampled hydrophone inputs, configurable sampling rates and internal solid state storage.

The TR-ORCA is easy to use, deploy and configure, and is flexible enough for almost any underwater acoustic measurement scenario. Applications include underwater noise characterization, marine mammal studies, underwater detection and localizations.

Your data can be recorded & processed autonomously or streamed in real time via Ethernet, or wirelessly with our TR-FLOAT unit.
