Often in deeper water USBL cannot be used as a DP position reference system as the noise (position jitter) causes the DP desk to reject the system. The time and hence cost of deploying and calibrating an LBL array for short term operations in these water depths can significantly impact the competitiveness of the vessel.

In addition to the inherent positioning jitter seen within USBL systems acoustic anomalies such as thruster noise and other interference are also detrimental to the reliability and accuracy of USBL.

By utilizing our “Clean USBL” smoothing solution in conjunction with your existing USBL system you can greatly improve the reliability and relative accuracy your USBL maintaining as a valid DP position reference sensor into the desk. Our USBL smoothing system effectively cleans your acoustic data in real time.

Our system can improve the relative accuracy of your USBL navigation by up to 70% as well as providing a reliable high update rate of position to the DP desk. Integrating the USBL smoothing system is a cost effective method for remaining compliant with class rules and providing a reliable additional position reference sensors.

Using our D-PINS system in conjunction with our USBL smoothing system you can add a critical layer of redundancy and reliability to your overall DP operations. Both products work seamlessly together with all USBL products on the market.
