NAVTRAK"® Model 482 DOPPLER DOCKING SONAR A precision docking sonar system which utilizes the Doppler prin-ciple to provide absolute "over-the-bottom" velocity information for berthing of super vessels. ? Velocity in 1 ft./min. increments (approx. 1/100 Knot) ? Fore/aft and port/starboard velocity at bow and stern ? Compensation for water temperature and salinity ? Portable displays ? Single transducer assembly installation ? fore and aft ? Built to meet MIL-E-16400, IEEE 45, and ABS standards ? Minimal installation cost ? Two-year maintenance ? World wide maintenance available With the advent of the super tanker and the deep keel, berthing and mooring of super vessels have become critical operations,. Edo Wes-tern's "Navtrak" can assist the pilot or captain in maintaining precise control of his vessel by means of accurate "over-the-bottom" velocity information. This information is completely independent of atmospheric conditions, ship dynamics, water currents, ship's engines, etc. During the critical operations of berthing or docking, it is absolutely necessary to have instantaneous velocity information (fore-aft, and port-starboard at the bow and stern) available to the captain or pilot. Relatively large kinetic energy levels such as encountered in super vessels require the most detailed information for the safety and pro-tection of ship and berth. Edo Western's "Navtrak" Docking System is completely independent of land based stations, and is contained entirely aboard the ship. The "Navtrak" was developed specifically to meet the docking require-ments of the large super vessel or tanker. Send for additional technical data and prices. IXMi/ corp.
