Master track of POLARSTERN cruise PS135/1 in 1 sec resolution (zipped, 8.5 MB)

Raw data acquired by position sensors on board RV Polarstern during expedition PS135/1 was processed to receive a validated master track which can be used as reference of further expedition data. During PS135/1 two Trimble Marine SPS855 GPS receivers and the iXBlue HYDRINS hydrographic survey inertial navigation system were used as navigation sensors. Data were downloaded from DAVIS SHIP data base (https://dship.o2a-data.de) with a resolution of 1 sec. 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.

本数据集针对极星号科考船（RV Polarstern）航次PS135/1搭载的位置传感器所采集的原始数据进行处理，得到经过验证的主航迹（master track），可作为后续科考航次数据的参考基准。本次PS135/1航次中，使用了2台Trimble Marine SPS855型GPS接收机与iXBlue HYDRINS水文勘测惯性导航系统作为导航传感器。原始数据从DAVIS SHIP数据库（https://dship.o2a-data.de）下载，时间分辨率为1秒。最终提供的处理后数据包含两类：一类是基于优先级筛选的位置传感器数据生成的1秒分辨率主航迹，另一类是对主航迹中的核心关键位置进行精简后得到的概化航迹（generalized track）。
