Blueye X3 Equipment

Micron Gemini Multibeam Sonar

The Micron Gemini fuses Tritech's Gemini multibeam technology with Tritech's Micron technology to create the world's smallest multibeam imaging sonar. It has a 90° horizontal field of view and a range of 50m. It has a speed of up to 20Hz, which makes it capable of recreating environments in real-time. Another advantage of this sonar is the compact size and light weight which does not affect the driving characteristics of the ROV.

Supplier
Tritech International Ltd

World’s smallest multibeam sonar

The Micron Gemini is the latest addition to Tritech’s Micron and Gemini product families and offers powerful, real-time sonar imaging in the body of a Gemini 720im.

With greatly improved image quality, a 90° horizontal field of view, and a 50 m range, the Micron Gemini offers cost-effective obstacle avoidance and navigation for the Blueye X3.

With Tritech’s advanced processing electronics, the Micron Gemini operates at 720kHz, to produce images of outstanding clarity. The system benefits from 128 beams and an effective angular resolution of 0.7°.
