Components
The EM712 consists of a transducer array for transmitting (Tx) and an array for receiving (Rx), the transceiver unit, the data aquisition PC with the aquisition software SIS and two processing PCs (bridge and Messraum) with the software Caris HIPS/SIPS.
The software "Seafloor Information System" (SIS) contains several graphic displays for quality checks and for system calibration as well as other tools. SIS supports an online/realtime data cleansing. Both SIS and the processing software Caris HIPS/SIPS are protected via a dongle. Please contact the bridge staff for suppport.
Sound velocity can alternatively been received from two sensors: from Sound Velocity Probe (Valeport Mini SVS) or calculated velocities from sensor Thermosalinograph.
Ships position is received from GPS Receiver Trimble Marine SPS461 . Ships orientation is received from Motion Sensor (PHINS).
