Marine acoustic hardware and systems supplier GeoSpectrum Technologies (GTI) has delivered a containerised version of its Towed Reelable Active Passive Sonar (TRAPS) to the Royal Canadian Navy (RCN).

The sonar is ready to be installed and operated on-board a naval vessel following the completion of the delivery.

The acquisition of the containerised version of TRAPS was carried out via the Build in Canada Innovation Program.

TRAPS is a new low-frequency (LF), variable-depth-sonar featuring a vertical projector and a receive array.

“We are proud to offer users a high-performance, lower cost and compact anti-submarine warfare (ASW) sensor that represents an excellent and available sonar choice.”

It is primarily designed to detect, track and classify submarines, midget submarines, surface vessels and torpedoes.

The sonar’s projector array is reelable and stows on the winch drum with the receive array and tow cable.

The trials conducted on the TRAPS system demonstrated its capability to tow the source at vessel speeds of more than 18k, while its receive array provides enhanced performance abilities with minimal self-noise.

GTI president Paul Yeatman said: “We are very pleased with results of TRAPS testing. We are proud to offer users a high-performance, lower cost and compact anti-submarine warfare (ASW) sensor that represents an excellent and available sonar choice for a wide variety of surface combatant and patrol vessels, as well as USVs, with a specific design available for Elbits’ Seagull multi-mission USV.

“TRAPS can be used by navies for anti-submarine operations, as well as coast guards for anti-Narco-Sub missions.”

The sonar can either be provided as a stand-alone system or as part of an integrated sonar-suite, which also includes a hull-mounted sonar and sonobuoy processor and features both bi-static and multi-static operation.
