ROV-Benthos Minirover MK II

ROV & Diver tracking

The DiveBase program is used for all for tracking operations, to replay existing mission records, configure DiveTracker stations, and perform noise tests. Accurate and reliable position information is key to successful ROV operations. Be it underwater inspection, construction, or search—you need a good tracking system to complete your job with confidence, efficiency, and speed. Pilot is the ideal tracking system for small and mid-size Rovs and Divers. The PILOT System: A Surface Station And A ROV Transponder

? The Surface Station is the centerpiece of the PILOT system. Three cabled sonar transducers (antennae for sound) are connected to the surface station and lowered over the side of the boat. The transducers form a triangle which is used to locate the ROV. A Windows 95, 98 or NT computer serves as the data display and entry unit. The Windows computer runs DiveBase, the surface station software. The ROV range, direction and depth appears on the BOAT RADAR style screen of DiveBase. ? The surface station will track any underwater vehicle that is equipped with a ROVTransponder . TLT-2 transponders are designed for tracking small ROV's to depths of 300 meters (1000 feet). It is suitable for mid-size ROV. And the VLT3HP-2 which is suitable for high noise hydraulic powered rov’s and is depth rated to a 1000 meters. Both can be tracked at the same time. For example the TLT on a diver and the VLT on a ROV or other object. Tracking Technology Short baseline acoustic tracking with three 'over the side' sonar transducers complemented by depth telemetry. Applications Optimized for tracking small & mid-size ROV, but also suitable for diver & AUV tracking or instrument recovery. Max. Range & Depth 500 meter range & 300 meter depth in basic configuration. Tracking Accuracy Slant range +/- 0.15 meter typical; depth +/- 1.5 meter; bearing accuracy depends on transducer separation: +/- 0.4 degrees with 50 meter baseline to +/- 4 degrees with 5 meter baseline. Number Of Targets Ten targets can be tracked. Surface Stations STM-1 module is mounted in a drive bay of a PC STM-1 is powered by PC 12V power. TLT-2 transponder attaches to ROV. The TLT-2 is battery powered and runs about 40 hours. TLT-2 transponder is rated for depths of up to 300 meters. The VLT3-HP ROV Transponders
which is suitable for high noise hydraulic powered rov’s and is depth rated to a 1000 meters. The VLT is internal rechargeable battery powered or external. This software runs on Windows 95 and NT machines. Features include tracking a single vehicle, ROV trace, color coded depth, numerical range, depth and bearing display, zoom and pan, various position filters, dive replay capability, extensive self tests and system status displays. Also includes multi-vehicle tracking, long baseline operation and diver/AUV navigation functions, capabilities to vector and bitmap boat chart overlays and BOAT GPS integrated operation. Software Features Multi-channel operation and short baseline technology yield excellent results in shallow, constricted and noisy waters with high multi-path as well as deep and o Operational Strengths p en waters.
