Master tracks in different resolutions of ELISABETH MANN BORGESE cruise EMB363, Rostock - Rostock, 2025-04-11 - 2025-04-14

Raw data acquired by position sensors on board RV Elisabeth Mann Borgese during expedition EMB363 were processed to receive a validated master track which can be used as reference of further expedition data. During EMB363 data from the motion reference unit exail Phins Gen.3, the Trimble SPS356 GPS receiver, the Furuno GP-170 and the Furuno GP-150 GPS receiver were used to calculate the mastertrack. Data were downloaded from DAVIS SHIP data base (http://dship.bsh.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track.

EMB363航次期间，搭载于伊丽莎白·曼·博格斯号研究船（RV Elisabeth Mann Borgese）的位置传感器所采集的原始数据，经处理后得到经验证的主航迹（master track），该航迹可作为后续航次数据的参考基准。EMB363航次期间，研究团队利用exail Phins Gen.3型运动参考单元、Trimble SPS356型GPS接收机、Furuno GP-170型及Furuno GP-150型GPS接收机采集的数据，计算得到该主航迹。相关数据从DAVIS SHIP数据库（http://dship.bsh.de）下载，采样分辨率为1秒。本数据集的数据处理与评估流程已在配套的数据处理报告中予以详述。本次发布的处理后数据包含两类：一类为按优先级筛选位置传感器数据后得到的1秒分辨率主航迹；另一类为选取主航迹中最关键位置点所构成的精简集合对应的简化航迹。
