Links to master tracks in different resolutions of POLARSTERN cruise PS122/2, Arctic Ocean - Arctic Ocean, 2019-12-13 - 2020-02-24 (Version 2)

Raw data acquired by position sensors on board RV Polarstern during expedition PS122_2 was processed to receive a validated master track which can be used as reference of further expedition data. During PS122_2 two Trimble Marine SPS461 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.awi.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report found at EPIC repository https://hdl.handle.net/10013/epic.1fdb256e-7b9c-4b61-9fbb-3e0dcf9d10ad. 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.

在极地考察船“Polarstern”执行PS122_2考察任务期间，通过船载位置传感器采集的原始数据经过处理，以获得经验证的主航迹，该航迹可被用作后续考察数据的参考。在PS122_2考察任务中，使用了Trimble Marine SPS461 GPS接收器和iXBlue HYDRINS海洋测绘惯性导航系统作为导航传感器。数据从DAVIS SHIP数据库（https://dship.awi.de）下载，分辨率为1秒。数据处理与评估的概述可在EPIC存储库中的数据处理报告中找到，链接为https://hdl.handle.net/10013/epic.1fdb256e-7b9c-4b61-9fbb-3e0dcf9d10ad。处理后的数据以主航迹形式提供，分辨率为1秒，由优先选定的位置传感器数据生成，并附带一个概括航迹，其中包含主航迹中最具代表性的位置集合。
