HYSWEEP driver for the Atlas Fansweep 15 and 20.  Also works with medium depth system MD2.  Provides roll corrected multibeam soundings, beam intensity values, port and starboard sidescan images and HPR compensation data.


Setup Form:

Use Heading From Sonar System:  User can select whether or not to use heading from the Fansweep.


Use Inbound Server:

If selected, datagram transfer uses a server application from Atlas.  If deselected, datagram transfer is direct into the driver.  Both methods work – the Inbound Server method is preferred as it has had more testing.



Only applicable if the Inbound Server is not used.  Set default Internet Address ( and Port number to match that set in the Fansweep control computer (20000 in one installation).


Offsets - MRU:

  • Starboard:  MRU location starboard of boat center.
  • Forward: MRU location forward of boat center.
  • Vertical: MRU location relative to waterline (positive below).
  • Yaw: Enter 0.
  • Pitch, Roll:  Enter 0 (MRU pitch/roll offsets are typically zeroed within the MRU itself).
  • Latency:  Enter 0.


Offsets – Sonar Heads 1 and 2:

  • Starboard:  Sonar head locations starboard of boat center.
  • Forward: Sonar head locations forward of boat center.
  • Vertical: Sonar head locations relative to waterline (positive).
  • Yaw, Pitch, Roll:  Sonar head rotations - enter values determined by patch testing unless already entered in the Fansweep (see note).
  • Latency:  Enter 0.



  • If sonar yaw, pitch and roll offsets are entered in the Fansweep, they must not be repeated in HYSWEEP setup.
