Tritech launches Gemini Multibeam Imaging Sonar
Tritech International Ltd has launched its next generation Gemini 720i multibeam imaging sonar. Gemini combines the benefits of long range detection with high-definition imaging techniques to produce outstanding results. With its lightweight, compact and robust design the Gemini can be easily deployed on most ROV and AUV platforms.
Weighing only 1.2 kg in the water, Gemini is ideal for ROV or AUV navigation and can be supplied with a Software Developers Toolkit (SDK) for autonomous control applications. Gemini is supplied with integrated Ethernet and VDSL communication modes which offer the option to communicate either through fibre optic cables or long distance twisted pair channels, depending on the configuration of the umbilical. All the sonar processing is carried out inside the subsea unit making it ideal for AUV control operations.
The introduction of a curved transmit transducer array ensures that acoustic energy power is evenly transferred across a wide swath imaging sector, thereby significantly speeding up search and navigation operations. To sharpen up the acoustic range resolution an innovative sound velocity sensor has been integrated into the design of Gemini to accurately monitor the local velocity of sound (VOS) conditions.
Building on Tritech’s reputation of customer-focused software interfaces, the Gemini architecture has been integrated into Tritech SeaNet Pro software making it compatible and easy to upgrade with the company’s range of survey and positioning sensors already deployed in the field.
Tritech’s Managing Director, Simon Beswick, commented on the launch:
“Gemini is a revolutionary product for subsea imaging, bringing extraordinary performance to our customers at a reasonable cost. The new multibeam technology will form the basis of a new range of very high performance products tailored to meet our customers’ requirements and complementing Tritech’s reference scanning sonars.”
