Micron Gemini Micron 300m

World’s smallest multibeam sonar with improved image quality

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 50m range, the Micron Gemini offers cost effective obstacle avoidance and navigation for small ROVs and AUVs, as well as utilisation with Tritech’s Diver Mounted Display system (DMD).

Product Description

To ensure the most detailed image possible, the Micron Gemini utilises advanced adaptive processing by switching between Compressed High Intensity Radar Pulse (CHIRP) and Continuous Wave (CW) modes of operation.

With incredibly compact dimensions, the Micron Gemini can be used in applications where size is critical but a small mechanically scanning sonar doesn’t offer the real-time imaging required. Alongside improved image quality, the Micron Gemini now includes a built in pressure sensor, depth sensor and optional AHRS.

The Micron Gemini is ideally suited for micro ROV/AUV applications when real-time, navigation 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.

The auxiliary port on the sonar allows for the daisy-chaining of sensors including the MicronNav 200 USBL Modem, Micron Battery Modem and Micron EchoSounder.

The Micron Gemini is supplied with Tritech’s Genesis integrated software suite which communicates with the sensor by using Ethernet or Tritech’s advanced Serial Multibeam Protocol (TSMP).
