Vessel: M.V. Ocean Endeavour. Equipment Type: Fugro Starpack 1 utilising Fugro Starfix XP2 corrections and Starpack 2 utilising Fugro Starfix HP corrections. Navigation Data Processing carried out using Gardline in house Voyager5 software. Raw navigation data were opened in Voyager5 and manually checked and corrected for any spikes or erroneous points. Once data cleaning has been carried out a light smooth filter of 11 points was added to the data which was then exported in shapefile format. The shapefile was opened in Global Mapper v15 and attributes were populated. Total Positional Uncertainty derived from the Fugro Starpack System â?? 0.1m. Every positions update and interpolated is plotted, data is not decimated. MBES Transducer Trackplots, Vessel: M.V. Ocean Endeavour Equipment Type: Fugro Starpack Navigation Package. Navigation Data Processing carried out using Gardline in House Voyager5 Software. Raw data were opened in Voyager5 and manually checked and corrected for any spikes or erroneous points. Once data cleaning has been carried out a light smooth filter of 11 points was added to the data which was then exported in a shapefile format. The shapefile was opened in Global Mapper v15 and attributes were populated. Total Positional Uncertainty derived from the Fugro Starpack Navigation System - 0.1m. No decimation is applied. Side Scan Sonar Towpoint Trackplots, Vessel: M.V. Ocean Endeavour Equipment Type: Sonardyne Ranger 2 USBL System. Navigation Data Processing carried out using Gardline in House Voyager5 Software. Raw USBL data were opened in Voyager5 and manually checked and corrected for any spikes or erroneous points. Once data cleaning has been carried out a light smooth filter of 11 points was added to the data which was then exported in a shapefile format. The shapefile was opened in Global Mapper v15 and attributes were populated. Total Positional Uncertainty derived from the USBL data - 0.4% at1DRMS. Total Positional Uncertainty derived from the Fugro Starpack Navigation System - 0.1m. Decimation Strategy is a point per beacon ping, update rate of every 1s. Magnetometer Towfish Trackplots, Vessel: M.V. Ocean Endeavour Equipment Type: Geometrics G882 Magnetometer and Sonardyne Ranger 2 USBL System. Navigation Data Processing carried out using Gardline in House Voyager5 Software. Raw USBL data were opened in Voyager5 and manually checked and corrected for any spikes or erroneous points.
