2018 Nautilus Quality Assessment Report

Cruise ID: NA093
Multibeam System: EM302
Dates: May 30 – June 3, 2018

  • Heading into the 2018 operating season, the EM302 and associated sensors aboard the E/V Nautilusare working well compared to the 2017 Quality Assurance Test (QAT) and earlier shipboard assessments.
  • The EM302 was calibrated for residual angular offsets using the Seapath 330+ as the primary positioning / attitude system. The patch test revealed that only very slight roll and heading adjustments were required. These biases were entered into the SIS installation parameters for Attitude 1 motion sensor, and should remain unchanged unless modifications are made to the system or there is evidence that another ‘patch test’ is necessary.
