Tritech Gemini Multibeam Imaging Sonar

Tritech Gemini Multibeam Imaging Sonar Incredibly compact and light-weight, operates at 720kHz, to produce images of outstanding clarity.

Tritech Gemini offering a cost-effective solution for obstacle avoidance and navigation for small ROVs/AUV. The system benefits from 128 beams and an effective angular resolution of 0.7. Powered with Tritech’s robust hardware and state of the art signal processing algorithms for producing high-quality sonar imaging. The system operates at 720 kHz and offers an effective angular resolution of 0.7° and a range resolution of 8 mm. In addition to compact dimensions and high quality imaging, it has integrated sensors for depth and temperature and an optional AHRS for bearing, roll and pitch

Tritech Micron Gemini real-time micro multibeam imaging sonar

The Micron Gemini is the latest addition to the Tritech’s Micron and Gemini product families. It is incrediblycompact and light-weight, offering a cost-effective solution for obstacle avoidance and navigation for small ROVs/AUVs. It is an obvious choice for the applications where size and weight are critical, but a small mechanical scanning sonar does not offer the required real-time imaging. With Tritech’s advanced processing electronics, the Micron Gemini operates at 720kHz, to produces images of outstanding clarity. The system benefits from 128 beams and an effective angular resolution of 0.7°.

The Micron Gemini comes with a built in pressure sensor which provides a depth reading, as well as optional AHRS. With greatly improved image quality, a 90° horizontal field of view and 50m range, the Micron Gemini offers cost effective obstacle avoidance and navigation for small ROVs and AUVs.

The Micron Gemini has incredibly compact dimensions and is ideally suited for micro ROV/AUV applications when real-time, video-like imagery is required, and where space is restricted or weight is critical, such as diver helmet and pole mounted applications for Search and Recovery (SAR) operations.
