Tritech Micron Nav USBL Positioning System
Description The Micron Nav system is an innovative USBL positioning system designed for small ROV / AUV. It has been primarily designed to be used in conjunction with the Tritech Micron / SeaSprite sonar and other Tritech Micro products. This concept will also be adapted and integrated into the Tritech SeaKing range of products in the future.

The system comprises of a subsea Micron Nav unit, a surface USBL transducer unit with integral Magnetic Compass and Pitch / Roll sensors, a surface Micron Nav 100 interface module and operating software under control of the customer host PC / Laptop.

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

It can be used as a stand-alone system, powered by and communicating with the Micron Nav 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 / SeaSprite sonar communicating via the sonar RS232 aux port.

The USBL transducer is designed to provide 180 degree hemispherical coverage below the transducer, allowing vehicle tracking in very shallow water. The design of the ROV Micron Nav transducer provides omni-directional coverage.
Features
  • Quick and easy to mobilise.
  • Integrated motion sensor in dunking transducer.
  • Seamless integration into Tritech Seanet Pro software control system.
  • Can connect via the 'aux port' of Tritech sonar systems - no need for extra umbilical communication channels.
Applications
  • Mini / Micro ROV navigation system.
  • Diver tracking system (optional transponder mode).
  • AUV tracking system (optional transponder mode).
  • ROV location beacon (optional transponder mode).
