Sonardyne has received an order to provide its SPRINT-Nav subsea navigation instruments for the Solus-LR long-range unmanned underwater vehicle (UUV) being designed for the Royal Canadian Navy.

The contract was awarded by subsea specialist Cellula Robotics, which is designing the new Solus- LR fuel cell-powered long-range UUV.

SPRINT-Nav is a combination of a SPRINT INS, Syrinx 600kHz DVL and a high accuracy intelligent pressure sensor incorporated in a single housing.

In addition to the SPRINT-Nav inertial navigation instrument, Sonardyne will provide a Micro-Ranger 2 Ultra-Short BaseLine (USBL) system with optional Marine Robotics software feature pack, and an AvTrak 6 combined transponder and telemetry transceiver. The equipment will be integrated into the Solus-LR.

Micro-Ranger 2 is an underwater target tracking system based on Sonardyne’s 6G hardware and Wideband 2 digital acoustic technology platform.

Cellula Robotics president Eric Jackson said: “This S&T programme will showcase Cellula’s advanced UUV research and development, combining traditional technologies with innovative power and anchoring solutions.

“With Solus-LR able to travel for thousands of kilometres, port to port missions will become a feasible lower-cost alternative to vessel-based operations.”

Cellula is under contract for the development of the Solus-LR UUV for Defence Research and Development Canada (DRDC), the Canadian Department of National Defence’s (DND) science and technology organisation.

The UUV is being developed under the country’s All Domain Situational Awareness (ADSA) Science & Technology (S&T) programme.

Through the ADSA S&T programme, the DND is providing support to projects that have the potential to develop solutions to increase domain awareness of air, maritime surface and sub-surface approaches to Canada.

“Port to port missions will become a feasible lower-cost alternative to vessel-based operations.”

Solutions are expected to boost the country’s capabilities, particularly in the Arctic.

Sonardyne will also provide support during the sea trials of the Solus-LR, supplying its Compatt 6 seabed transponders and BlueComm 200 underwater optical communication instruments.

The trials are expected to start later this year in the Indian Arm fjord, near Vancouver, British Columbia.

In November last year, Cellula won a contract from the Canadian Government to continue development of the Solus-LR.
