- Cerulean Bar30 depth/pressure sensor
- Foldable mount with housing/fairing for MBES
- Data cable with connector for SkyHub onboard computer
- Transport case
Surveyor 240-16 is a 240 kHz multibeam echo sounder (MBES). It has a transmit beam approximately 4 degrees along track, 80 degrees cross track, and a 16-element receive array.
Surveyor 240-16 utilizes an angle-of-arrival estimation algorithm to measure cross track location of specific acoustic reflectors well in excess of the accuracy achievable with conventional beam-forming techniques. Thus, although the effective cross track beam width with conventional beam forming is about 7 degrees, Surveyor can resolve angle of arrival to less than one degree.
Depending on the range and acoustic properties of the bottom, Surveyor typically identifies 10-15 acoustic targets across track within a swath width of 80 degrees. The position and depth of these targets are then accurately calculated by range and angle of arrival.
Surveyor includes a built-in IMU for pitch and roll. Heading and coordinates for data geotagging are coming from the drone.
Comes with an Ethernet interface and connector for SkyHub.
Please note that additional components and software must be purchased to use this sensor with drones. A complete set of required items will be proposed when you request the quote.
