Trials and testing of new swath sonar systems

One of the major roles of the OMG over the past 8 years has been the trial and testing of new or upgraded swath sonars. This originally was done on an informal basis for the CHS as each new sonar or peripheral sensor came on line.

• 1991/2 CSS Matthew EM100
• 1992/3 - CSS Frederick G. Creed EM1000
• 1994/5 – CSS Frederick G. Creed Applanix POS/MV
• 1996/7 - CSS Puffin/Plover/Petrel EM3000S
• 1999 - CCGS Young EM1002

This has since taken a turn whereby other swath systems being mobilized are checked, analyzed and calibrated by OMG staff. In recent years this has included:

• 1996 – EM1000, C&C Technologies – USGS Seafloor Mapping Program
• 1997 - EM300, C&C Technologies – USGS Seafloor Mapping Program
• 1998 - EM3000D, C& C Technologies – USGS Seafloor Mapping Program
• 1999 - ATLAS MD2/30, Royal New Zealand Navy
• 1999 - Simrad EM1002 Clearwater Fine Foods.
• 2000 - ATLAS Fansweep 20-100, Royal Australian Navy

This work provides a unique opportunity to quantitatively assess the capability of newly emerging hardware. This information can be used to update training material and to redirect current research thrusts to take account of the rapid advances in technology seen in the marketplace.
