Master track of SONNE cruise SO287 in 1 sec resolution (zipped, 14.5 MB)

Raw data acquired by position sensors on board RV SONNE during expedition SO287 were processed to receive a validated master track which can be used as reference of further expedition data. During SO287 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.

SONNE号考察船（RV SONNE）在SO287航次期间通过船载位置传感器获取的原始数据经过处理后，得到了一条经过验证的主航迹（master track），可作为后续航次数据的参考。SO287航次中使用的导航传感器包括Kongsberg SeaTex AS公司的MRU-5运动参考单元（motion reference unit）、Kongsberg SeaTex AS公司的Seapath 320以及两台SAAB MGL-4 GPS接收机。数据从DAVIS SHIP数据库（https://dship.bsh.de）下载，分辨率为1秒。数据的处理与评估过程详见数据处理报告。处理后的数据以两种形式提供：一是基于优先级筛选的位置传感器数据生成的、分辨率为1秒的主航迹；二是主航迹中关键位置简化后的通用航迹（generalized track）。
