Master tracks in different resolutions of POLARSTERN cruise PS133/1, Cape Town - Punta Arenas, 2022-10-02 – 2022-11-17

Raw data acquired by position sensors on board RV Polarstern during expedition PS133/1 was processed to receive a validated master track which can be used as reference of further expedition data. During PS133/1 one Trimble Marine SPS852 GPS receiver, one Trimble Marine SPS855 GPS receiver 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.

在北极星号（RV Polarstern）RV Polarstern的PS133/1考察期间，通过船载位置传感器采集的原始数据经过处理，得到了一个经过验证的主航迹，该航迹可被用作后续考察数据的参考基准。在PS133/1考察中，使用了Trimble Marine SPS852 GPS接收器、Trimble Marine SPS855 GPS接收器和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.awi.de）下载，分辨率为1秒。处理后的数据以1秒分辨率的航迹形式提供，该航迹由优先选定的位置传感器数据生成，并辅以主航迹中最为关键位置点的集合，形成了一个通用的航迹。
