MicronNav 200 Tracking System
The latest generation of MicronNav Systems is an innovative USBL tracking system designed for small ROV/AUV
Excellent USBL Tracking system for small vehicles, ROVs, AUVs and diver applications.
Description
The system benefits from a number of new features including data transfer interleaved with USBL positioning, software integration into Google Maps™, smaller, more accurate USBL head and compatibility with the new Micron Battery Modem.
The system comprises a subsea Micron Modem or Battery Micron Modem, a surface USBL transducer with integral magnetic compass and pitch/roll sensors, a surface MicronNav 200 interface hub and bespoke operating software under control of a topside PC/laptop.
The MicronNav 200 uses spread spectrum acoustic technology. This provides a robust method for communication between the dunking transducers and the vehicle Micron Modem/Micron Battery Modem.
The USBL transducer can provide 180 degree hemispherical coverage below the transducer, which allows vehicle tracking in very shallow water. Omni-directional coverage is provided by the Micron Modem and Micron Battery Modem.
The Micron Modem is a stand-alone device which either responds to acoustic interrogation from the USBL head (transponder mode), or is triggered by RS232 / RS485 (responder mode) through the main port. The responder trigger can come either from the auxiliary port on a Tritech Micron Sonar, or directly from the MicronNav 200 interface hub.
Both the USBL transducer and the Micron Modem/Micron Battery Modem can be commanded to switch from positioning mode to data transfer mode, allowing the same hardware to be used to establish an underwater acoustic communications link.
