Master tracks in different resolutions of HEINCKE cruise HE639, Bremerhaven - Bremerhaven, 2024-05-08 - 2024-05-14

Raw data acquired by position sensors on board RV Heincke during expedition HE639 were processed to receive a validated master track which can be used as reference of further expedition data. During HE639 the inertial navigation system IXSEA PHINS III and the GPS receivers Trimble Marine SPS461 and SAAB R5 SUPREME NAV 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.

本数据集源自海因克号（RV Heincke）在HE639航次期间由船载位置传感器（position sensors）采集的原始数据，经处理后得到经过验证的主航迹（validated master track），可作为后续航次数据的参考基准。本次HE639航次所使用的导航传感器包括惯性导航系统（Inertial Navigation System）IXSEA PHINS III，以及GPS接收机（GPS Receiver）Trimble Marine SPS461与SAAB R5 SUPREME NAV。原始数据从DAVIS SHIP数据库（DAVIS SHIP data base，https://dship.o2a-data.de）下载，采样分辨率为1秒。处理后的数据包含两类成果：一类是基于按优先级筛选的位置传感器数据生成的1秒分辨率主航迹；另一类是对主航迹的核心关键位置进行精简后得到的广义航迹（generalized track）。
