Gemini 720is - Multibeam Imaging Sonar

Industry Sectors:

Academic & Research, Energy, Engineering, Survey, Underwater Vehicles

Tritech’s Gemini multibeam imaging sonar provides users with real-time, crisp imagery for applications including obstacle avoidance, target detection, and close-range inspection. Now with the latest electronics Tritech presents the next generation Gemini 720is imaging sonar.

With a 120 degree field of view (10-degree tilt) and a fast update rate of 30Hz, the Gemini 720is sonar is ideal for poor visibility environments. Gemini 720is features a 720 kHz operating frequency and an integrated sound velocity sensor to assist in providing the sharpest image possible, with accurate ranging. Redesigned for ease of installation onto a variety of ROVs, AUVs, and other underwater platforms, the Gemini 720is operates through Ethernet or VDSL communications. The sonar’s compact size means that it can also be deployed using a pole-mount assembly (customer supplied).


The Tritech Seanet Pro software package supports the Gemini 720is enabling a network of other Tritech sensors. A standalone Gemini software package is also available which offers users a tailored control and display interface including a click and track function and engineering measurement tools. Gemini software has typical features common with Seanet Pro such as data recording/ playback, screen capture, range and gains control, color palette selection, cursor reporting. A software development kit is available for autonomous vehicle operations.

Gemini SeaTec – Marine Object Tracking and Target Detection

There is the option to upgrade the standalone Gemini software to the Gemini SeaTec software for target tracking and classification applications.

Gemini SeaTec is specifically designed to detect objects and subsequently, classify targets accordingly. Housing changes can be made to suit specific deployment requirements.

Applications using the Gemini SeaTec software have included the tracking and detection of marine life around subsea turbine structures.
