Cerulean Sonar Device / Instrument
Sounder S500
500 kHz CHIRP single-beam echosounder for small ROVs, AUVs and ASVs, usable as altimeter, bathymetry sounder or obstacle avoidance sonar.
Description
The S500 is a multipurpose single-beam echosounder with unbundled transducer and control electronics to minimize external profile. The transducer (54mm diameter x 22mm) is rated to 300m and the electronics module sits inside the vehicle's pressure enclosure.
Key features
- 500kHz transducer, about 5° beam width, 100m+ range
- CHIRP modulation for better signal-to-noise and range resolution
- On-device bottom-tracking algorithm; can output distance or full signal profile (waterfall)
- Ethernet, USB and 3.3-5.0V serial interfaces; supported by SonarView
Applications
ROV/AUV altimeter, USV bathymetry, obstacle avoidance and underwater distance measurement.
