contenttypeSummary

Multibeam EM712 is a high-resolution seafloor mapping system. It is suitable for water depths up to 2000m depending on the configuration of the transducers. Maximum ping rate is 30Hz and maximum fan width 140° 140° and depth resolution 1cm. Data from the water column may also be stored.

The GPS position of the Trimble GPS receiver antenna is stored in the data files. The position is NOT centralized to the SES2000 transducers. Heave correction between the motion sensor and the transducer are calculated in the motion sensor and corrected values are transferred to the SES2000. Time synchronisation is achieved via NTP. Centralization of the GPS position to the transducer is achieved by  SIS software. GPS antenna position and transducer position related to the motion sensor position as a reference point are stored in the data files. Pay attention that in case of failure of the Trimble GPS sensor the Saab GPS sensor may be used as the reference GPS source. Please contact the bridge staff for information about the GPS receiver in use. Heave correction values are only available for the Trimble GPS receiver. Heave correction between the motion sensor and the transducer is calculated 
in the EM712 transceiver unit. UTC time synchronisation of the transceiver unit is achieved via GPS with PPS. The PC is synchronised with UTC via the Windows-Domain-Affiliation to ensure a correct naming of the data files.

Rawdata storage on board
The data acquisition software SIS creates raw data on the local drive of  the computer. The EM712 data are not transferred to DSHIP.
