Coda Octopus MRU F180 Inertial Navigation and Attitude Measurement System


Coda Octopus MRU F180 Inertial Navigation and Attitude Measurement System

Accurate, reliable MOTION and positioning data in a compact package

The F180® series of GNSS aided inertial attitude and positioning systems are high quality, compact packages for the hydrographic survey market.

Refined to meet the exacting requirements of the multibeam survey market, the F180® series systems are easy to install, easy to use and produce highly accurate positioning, heading and MOTION data in the most dynamic offshore conditions.

The light, yet robust equipment has proved to be a reliable and cost effective solution on marine survey vessels of all sizes.

iHeaveTM (Intelligent Heave) processing is included as standard to accurately measure swell amplitudes of up to 70 seconds period.

A GLONASS upgrade is available to allow your F180® series system to utilise additional satellites, especially useful in areas where the sky view is partially obscured.

Additionally, for extremely rapid vessel deployments, we produce a PreCalibrated housing accessory to significantly reduce the installation and calibration phases of operation.
