2018 Thompson EM302 SAT Report
11/28/2018 — adminConducted January 8-12, 2018 to test the new Kongsberg EM302 (upgraded from EM300) and Applanix POS MV V5.
E/V Nautilus Spring 2017 Quality Assessment Report
09/06/2017 — adminSummary and Recommendations:
RV Sikuliaq 2016 Calibration Report
12/30/2016 — adminThe R/V Sikuliaq is equipped with Kongsberg Maritime (KM) EM302 (30 kHz) and EM710 (70-100 kHz) multibeam echosounders and a Seapath 320 positioning and attitude system with C-NAV DGNSS auxiliary input. These systems were reviewed by the Multibeam Advisory Committee (MAC) and personnel from NOAA, the University of Alaska Fairbanks (UAF), and Kongsberg Maritime (KM) during sea acceptance trials (SAT) in August 2014.
RV Bat Galim 2016 System Review
06/24/2016 — adminFrom January 31st to February 4th, 2016 a Shipboard Acceptance Testing (SAT) was conducted on the R/V Bat Galim, owned by the Ministry of National Infrastructures, Energy and Water Resource of Israel and operated by Israel Oceanographic and Limnological Research, on the newly installed Kongsberg Maritime (KM) EM302 (30 kHz) and EM2040 (200 kHz, 300 kHz, and 400 kHz) multibeam echosounders. These systems were thoroughly reviewed for system geometry, calibration, configuration, and performance during this acceptance period. Documented in this report are:
RV Bat Galim 2016 Acoustic Test Report
06/24/2016 — admin- The overall noise levels of BAT GALIM were measured and characterized with special test sensors and internal noise routines inherent in the Kongsberg sonars.
- Propeller cavitation characteristics were assessed.
E/V Nautilus Spring 2014 Quality Assessment Report
05/15/2015 — adminSummary and Recommendations
- As it stands now, the EM302 and associated sensors are working well as compared to other EM302s evaluated recently. The patch test revealed very slight residual angular offsets, indicating a successful reinstallation of the MRU and no apparent change to any other component of the system.
E/V Nautilus Spring 2015 Quality Assessment Report
05/15/2015 — adminSummary and Recommendations
- Heading into the 2015 operating season, the EM302 and associated sensors aboard E/V Nautilus are working well compared to previous evaluations and to other EM302 systems examined recently. The patch test showed no pitch or yaw bias and only a very slight residual angular offset for roll, indicating no major changes to the system geometry.
Sikuliaq 2014 Acoustic Test Report
11/26/2014 — adminGates Acoustic Services was tasked by University of Alaska, Fairbanks, to investigate and quantify acoustic issues associated with operation of the R/V SIKULIAQ. An at-sea investigation was accomplished during ship operations in deep water out of San Juan, Puerto Rico on September 12-18, 2014.
