Master tracks in different resolutions of POLARSTERN cruise PS135/2, Mindelo - Bremerhaven, 2023-03-28 – 2023-04-11

Raw data acquired by position sensors on board RV Polarstern during expedition PS135/2 was processed to receive a validated master track which can be used as reference of further expedition data. During PS135/2 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.awi.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.

在极地考察船Polarstern上通过位置传感器收集的原始数据，经过处理，获得了一道经过验证的主轨迹，该轨迹可作为后续考察数据的参照。在PS135/2考察期间，使用了Trimble Marine SPS855 GPS接收器和iXBlue HYDRINS海洋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.awi.de）中以1秒的分辨率下载。处理后的数据以1秒分辨率的轨迹形式提供，该轨迹从优先选定的位置传感器数据中提取，并包含主轨迹中最重要的位置集合的广义轨迹。
