Datasheet

Key System Features:

  • Configurable sampling rates up to 384 kHz
  • Low Power
  • Real-time data streaming of raw audio
  • Up to 4 TB removable SD storage
  • Internal battery and optional external battery packs
  • Embedded hydrophone or third party hydrophone via connector
Porpoise, helped in development by RS Aqua, takes all the processing power and real time data streaming capabilities of its big brother, the Orca, and compresses it into a compact and streamlined single-channel package.

Thanks to its small size, the Porpoise is very easy to deploy and use, meeting the requirements for a variety of underwater acoustic measurement projects. Current applications for Porpoise include ambient noise monitoring and characterisation, construction monitoring and marine mammal research. The Porpoise can be deployed for 48 hours using internal power, or 182 Days with an external 36 D cell pack, while configured for Continuous Recording at 384 ksps sampling rate.

Real time configuration, analysis and visualisation software called TRAC is supplied with every Porpoise. It allows users to easily setup their instrument parameters including enabled channels, sampling rates, channel gain and recording schedules. With highly configurable sampling rates, intelligent on/off scheduling and configurable hydrophone settings, Porpoise is truly the smartest single-channel system available.

RS Aqua are also able to provide ClearSignal® anti-fouling coating to Porpoise as an in-house service to reduce the impact of biofouling on your instrument.
