VideoRay ROV - Tritech MicronNav USBL Positioning System

The MicronNav positioning system is an innovative USBL tracking system designed for small ROVs like the VideoRay. It has been primarily designed to be used in conjunction with the Tritech Micron sonar and other Tritech Micron products such as the Micron Echo Sounder altimeter.

MicronNav uses the very latest in Spread Spectrum acoustic technology, which provides a robust method for communications between the dunking transducers and the vehicle responder/ transponder.

The USBL Tracking System can be used as stand-alone unit, powered by and communicating with the MicronNav through a spare RS232 port on the ROV (at 9600 baud) or RS485 through a spare screened twisted pair in the umbilical. Alternatively it can be integrated with the Tritech Micron sonar communicating via the sonar RS232 aux port.

The USBL transducer is designed to provide 180° hemispherical coverage below the transducer, allowing vehicle tracking in very shallow water. The design of the ROV MicronNav transducer provides omni-directional coverage.

Typical VideoRay ROV / MicronNav applications are:

  • ROV Navigation
  • Offshore Oil & Gas
  • Hull & Structure Inspection
  • Multiple Target Observation
  • Search and Rescue / Recovery

The system comprises of a subsea MicronNav unit, a surface USBL transducer unit with integral Magnetic Compass and Pitch / Roll sensors, a surface MicronNav 100 interface module and operating software under control of the VideoRay Pro 4 computer and Cockpit Software.  The system is also compatible with VideoRay Pro 3 ROV systems via a user-supplied laptop.

Open Enrollment Certified VideoRay Training is available for MicronNav and is included with any VideoRay Pro 4 ROV configuration containing a MicronNav positioning system.
