Seafloor - Model PicoMBES-120SF -Miniature CHIRP FM Multibeam Echosounder

PicoMBES-120SF is a low-cost, miniature CHIRP FM multibeam echosounder (MBES), customized to fit inside the transducer well of the EchoBoat™. The EchoBoat is a 1.68m remotely controlled and autonomous surface vehicle that can be used to perform multibeam surveys in very shallow water or in remote areas where it is difficult to launch conventional survey boats. PicoMBES-120SF features rugged, fully encapsulated transducers and an aluminum topside with optional integrated Applanix INS. All beamforming and digital signal processing are performed within the sonar, allowing a direct connection from the sonar to a computer via Ethernet, or Android smartphone/tablet via WiFi. GNSS and IMU connect to the sonar - no rack-mounted hardware is required. Android and Windows GUIs are provided for real-time display and recording. The Android app features a real-time 3D point cloud allowing bathymetric data to be acquired using a tablet or smartphone in an Aquapac.
