Simrad WBAT

The Simrad WBAT Autonomous scientific echo sounder system allows you to do continuous long term, in-depth ecosystem monitoring of the subsea environment using cutting-edge technology.

The Simrad WBAT uses wideband echo sounding technology to discriminate between plankton and different fish species producing high-quality, high resolution scientific data.

Simrad WBAT

The WBAT Transceiver comprises a rugged cylinder providing all necessary transmitter and receiver electronics, a battery and the necessary interface and control circuitry.

The Simrad WBAT is at the forefront of monitoring marine life capable of being submerged to a maximum depth of 1500 meters and prolonged periods of up to 15 months. When deployed, the WBAT is selfcontained and will record data with the acoustic settings at the given time intervals. Between data recording events the WBAT will be in “deep sleep” conserving energy and extending battery life.

Proven technology

The Simrad WBAT uses the same technology as the Wide Band Transceiver (WBT), but it has been redesigned for a compact and energy-efficientsolution. Four independent channels can be used as multiple single-beam channels, or working together with a split-beam transducer. With the built-in multiplexer you can also connect two split-beam transducers simultaneously using sequential pinging.

The advantage of the WBAT is that you can collect data in a format, and of a quality, that you already know from the Simrad EK80 scientific echo sounder. Regardless of whether the data is collected from the ship sounders, a profiling probe, or fromother platforms; the echo sounders use the same data format. This means that the data from different sources can be easilyintegrated. As with the EK80, the WBAT is capable of split-beam operation, which means that it can be calibrated to the same standards and with the same methods as the EK80.

The pressure rated housing used by the Simrad WBAT, along with the connections and the internal battery, are already proven Kongsberg Maritime technology. These components have been used in our transponders for many years.
