Gemini 1200ikd
Compact dual-frequency multibeam imaging sonar keeping a 120° field of view at 720 kHz and 1200 kHz; aluminium, rated to 500 m or 1000 m.
Description
The Gemini 1200ikd is a compact dual-frequency multibeam imaging sonar that maintains a 120° field of view across both operating frequencies. Keeping the full field of view at high frequency means the target stays in view when working at short range.
Key features
- 720 kHz / 1200 kHz operation with maximum range of 120 m / 50 m
- Range resolution down to 2.4 mm and effective angular resolution down to 0.12°
- Acoustic angular resolution of 1.0° / 0.6°
- Vertical beamwidth of 20° / 12°
- Ethernet communications, 19 to 74 V DC supply, 9.5-27 W depending on range
- Aluminium housing with 500 m or 1000 m depth rating
Applications
Inspection and observation ROVs and AUVs requiring high-definition imaging for navigation, obstacle avoidance and close-range target identification.
