NGS Helps Improve Performance of NOAA Ship Henry B. Bigelow

The National Geodetic Survey (NGS) completed a component spatial relationship survey aboard the NOAA Ship Henry B. Bigelow while it was in dry dock in Charleston, South Carolina, the week of July 23. NOAA's Office of Marine and Aviation Operations requested the survey, which accurately positioned the ship's multibeam sonar sensor, Inertial Measurement Unit, and GPS antennas. The field survey of each component was tied to the ship's coordinate reference system, allowing the components to work in unison while collecting necessary field data. NGS's work will help the vessel obtain better positioning along the sea floor, thus improving the overall accuracy of the collected hydrographic data. For more information, contact Perky Falconer.
