Master track of SONNE cruise SO288 in 1 sec resolution (zipped, 14.2 MB)

Raw data acquired by position sensors on board RV SONNE during expedition SO288 were processed to receive a validated master track which can be used as reference of further expedition data. During SO288 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.

在SO288科考航次期间，松纳号（RV SONNE）船载位置传感器采集的原始数据经过处理，得到经过验证的主航迹（master track），可作为后续航次数据的参考基准。本次SO288航次所使用的导航传感器包括康斯伯格海泰克斯（Kongsberg SeaTex AS）MRU-5运动参考单元、康斯伯格海泰克斯Seapath 320设备以及两台SAAB MGL-4型GPS接收机。原始数据从DAVIS SHIP数据库（http://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：一类是基于按优先级筛选的位置传感器数据生成的1秒分辨率主航迹，另一类是从主航迹中精简提取关键位置点得到的概略航迹。
