Master track of POLARSTERN cruise PS143/1 in 1 sec resolution (zipped, 116 MB)

Raw data acquired by position sensors on board RV Polarstern during expedition PS143/1 was processed to receive a validated master track which can be used as reference of further expedition data. During PS143/1 two Trimble Marine R750 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）PS143/1航次期间船载位置传感器采集的原始数据开展处理，生成经验证的主航迹（master track），可作为后续科考航次数据的参考基准。本次PS143/1航次期间，搭载两台Trimble Marine R750型GPS接收机与iXBlue HYDRINS水文测量惯性导航系统作为导航传感器。数据从DAVIS SHIP数据库（https://dship.o2a-data.de）下载，采样分辨率为1秒。最终提供的处理后数据包含两类：其一为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；其二为对主航迹中最具代表性的位置进行精简后得到的概化航迹。
