Metrology

4D Nav's metrology solution allows you to perform consistent calculations and streamline subsea metrology operations. This application provides offshore teams with an all-in-one solution for project planning, data collection, analysis, and LBL network adjustments. The application will then use the finalized data to perform the critical metrology calculations and complete the reporting process.

Flexibility

NavView's metrology application has the flexibility required to tackle the most complicated metrologies. From simple hub to hub vertical metrologies to complex "close-out spool" horizontal metrologies, the software has the capability to complete all tasks associated with the calculations without the need for uncontrolled spreadsheets.

Streamline subsea metrology operations

4D Nav's unique ability to connect directly to both Sonardyne 6G and 6G+ hardware makes this software application a must-have for metrology campaigns.

Effortlessly importing vital metrics and data, including LBL acoustic, dimensional control, inclinometer, gyrocompass, sound velocity, and pressure data, allows for a very comprehensive software package to cover all aspects of metrology without the need for other third-party software products.

Using a cascading calculation method, starting with attitude data, then a vertical least squares adjustment of depth data, and finishing with a horizontal network adjustment of the acoustic range, 4D Nav's built-in statistical modeling makes it quick and easy to identify outliers and erroneous data sets to complete the final metrology calculations with precision and confidence.
