Vessel: Rainier
Multibeam System: EM710
Dates: June 2013
Sensor geometry reconfiguration was successfully completed and tested on Rainier and a 14 ms orientation time delay was applied in SIS to accommodate an observed latency in the transmission of motion data from the POSMV to SIS. We feel that these two modifications will improve the data quality with the geometry reconfiguration allowing for successful application of TrueHeave in post-processing and the time-delay configuration improving the data quality of soundings as corrected in real-time by SIS. Minor changes to TrueHeave and SBET importing into CARIS will allow for application of the time delay such that the POSMV and SIS data streams are synchronized.
