The Micron INS is supplied in a single subsea bottle equipped with integrated core inertial sensors, attitude sensor and a depth sensor. The system has a mounting bracket available and this, along with additional software configuration utilities, makes vehicle integration easy, accurate and reliable. The Micron INS calculates heading, position, attitude, velocity and depth using high rate data from an advanced miniature core MEMS Inertial Measurement Unit aided by an integrated high accuracy pressure sensor and triaxial set of magnetometers.
The Micron INS also supports integration with USBL, DVL, altimeter and GPS units for increased accuracy. Proprietary time correlation algorithms and an Extended Kalman Filter (EKF) optimally fuse and filter the data from these various integral and external sensors to provide a robust navigational solution. The Micron INS is fully supported through Tritech’s MicronNav USBL system for integration and operation with Tritech’s subsea navigation products. A stand-alone Graphical User Interface (GUI) also provides a rich 2D chart plotting, navigation and diagnostics display as well as configuration utilities for commissioning and testing the Micron INS.
When used in conjunction with a Tritech sonar, the user benefits from the multiplexing capabilities of Tritech products, removing the need for additional communication channels on the ROV. The Micron INS is constructed around a modular software architecture, allowing Tritech to offer optional software modules which can expand the capability of the base Micron INS system.
