MacArtney Announces

DIDSON Milestone

MacArtney A/S said that they have both a Standard and a Diver Held

DIDSON available for test, demon- strations and rental. So far

MacArtney A/S are demonstrating the systems to military clients, com- mercial inspection companies, police authorities and fisheries research institutes, to name a few.

DIDSON sets a new standard for imaging sonars and high-definition sonars. It gives near video quality images for inspection and identifica- tion of objects underwater. It is a sur- rogate for optical systems in turbid water. The Standard DIDSON oper- ates at two frequencies (1.8 MHz and 1.1 MHz) and provides images of objects from one meter to over 30 meters in range. DIDSON LR oper- ates at 0.70 MHz and 1.2 MHz and can image objects out to 80 meters.

DIDSON is small and requires only 30 watts. MacArtney's current mod- els operate at depths to 300 m.

The Diver Held DIDSON is a self- contained unit with batteries and mask-mounted display. It allows divers to operate in zero-visibility conditions. The Diver Held DID-

SON was developed to inspect hulls and berths in turbid water where divers otherwise would resort to slow, tactile examinations.

Werum Software & Systems

Werum Software & Systems, Germany, introduced Perplex, a computer-aided system for dynamic planning and execution of scientific maritime expeditions. Perplex, which stands for 'Program for Expedition Route, Planning and

Execution' is designed to substantially simplify the complex and time consuming process of planning with research vessels. It aims to make cruise planning easier, faster, and more comfortable. Perplex contains routines to set up the cruise track with waypoints and stations which can be rearranged in any desired order. Stations can be inserted or modified and ship speed between waypoints may be prescribed. The software will automatically update the cruise schedule. In addition, Perplex pro- vides menus to edit the cruise sched- ule and merge the calculated sched- ule with the real date and time. At any stage the cruise plan is presented as a list and plotted on a map.
