Master tracks in different resolutions of SONNE cruise SO307, Durban - Durban, 2024-09-12 - 2024-10-28

Raw data acquired by position sensors on board RV SONNE during expedition SO307 were processed to receive a validated master track which can be used as reference of further expedition data. During SO307 the motion reference unit Kongsberg SeaTex AS MRU-5 combined with Kongsberg SeaTex AS Seapath 320 and two GPS receivers SAAB MGL-4 were used as navigation sensors. 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.

本数据集源自SO307科考航次期间松尼号（RV SONNE）船载位置传感器采集的原始数据，经处理后得到经验证的主航迹（master track），可作为后续航次数据的参考基准。SO307航次中使用的导航传感器包括：康斯伯格SeaTex AS（Kongsberg SeaTex AS）MRU-5运动参考单元、康斯伯格SeaTex AS Seapath 320系统，以及两台萨博（SAAB）MGL-4型GPS接收机。原始数据从DAVIS SHIP数据库（https://dship.bsh.de）下载，采样分辨率为1秒。数据的处理与评估流程详见数据处理报告。本次提供的处理后数据包含两类航迹：一类为按优先级筛选位置传感器数据生成的1秒分辨率主航迹；另一类为对主航迹关键位置进行精简后得到的概略航迹（generalized track）。
