Tritech Gemini NBI – Narrow Beam Imaging
The Gemini NBI offers a narrow vertical beam and 130 swath. The Gemini NBI produces an acoustic image, cutting through the water with a narrow acoustic beam and at the high refresh rate users can expect from the Gemini range.
Description
The Gemini NBI produces an acoustic image, cutting through the water with a narrow acoustic beam and at the high refresh rate offered from the Gemini range of multibeam sonars. Based on the proven design of the Gemini 720i, the Gemini NBI uses a 1° vertical beam instead of the 20° vertical beam found previously. The Gemini NBI’s reduced beam width allows the user to more precisely identify the position of the acoustic targets than is possible with a wide beam imaging sonar.
Applications
- Pipe and cable lay tracking
- Trenching operation monitoring
- Mining visualisation
- ROV/AUV navigation
Benefits
- High speed updates
- 4000m titanium housing
- Solid-state design reliability
- Easy to use software package
Features
- Ethernet or VDSL communication
- 130° swath
- 1° vertical beam
- 0.5° effective angular resolution
Operating at 620kHz the Gemini NBI is able to produce images with 10mm range resolution while the 0.5° horizontal angular resolution results in an extremely sharp sonar image. Where monitoring your position relative to a known target is the objective, and not general obstacle avoidance, then the Gemini NBI can help guide you safely to the desired target.
