Among other features normally included are system (sensor)
calibration, survey planning, helmsman display and the full use
of the chosen operating system for data export, plotting and
printing. Support is provided for displaying electronic map data
as a background in the geographical displays. Optionally the
raw beamformed data may be logged or shown as a water
column sonar display. Also optionally the raw hydrophone data
(before beamforming) may be logged.

Data logging
Ensuring logging of all data is of the utmost importance in the
system. The data is always stored on disk and the geographical
displays take data only from disk so that that what the operator
sees is what is safeguarded. As standard there are two high
performance SerialATA disks connected in a RAID1 array, i.e.
one disk may fail without loss of data. The disks are mounted in
mobile storage bays, thus they may be removed for security
reasons or to transport the acquired data directly. The system
disk has plenty of space to back up data or the data may be
written to DVD at any time. The Firewire, SCSI and USB
interfaces may be utilized for transfer of data to external
storage devices such as disk or tape according to user
preferences. All data are also available on an external Ethernet.
Logged data include raw sensor data, beam ranges and beam
pointing angles. In a depth datagram these data have been
combined to derive a rigorous solution for vessel motion and
raybending giving sounding depth and position as Cartesian
coordinates. Also available for logging is the gridded data. The
data formats are public ensuring that data may be used with
other software.
