Master track of HEINCKE cruise HE568 in 1 sec resolution (zipped, 0.9 MB)

Raw data acquired by position sensors on board RV Heincke during expedition HE568 were processed to receive a validated master track which can be used as reference of further expedition data. During HE568 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. Processing and evaluation of the data is outlined in the data processing report found at EPIC repository https://hdl.handle.net/10013/epic.e4ce4177-53dc-4a00-a678-cecacd7a3de1. 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.

本数据集由“海因克号”（RV Heincke）研究船在HE568航次中搭载的位置传感器采集的原始数据处理生成，得到经验证的主航迹，可作为后续航次数据的参考基准。HE568航次期间，研究团队采用惯性导航系统IXSEA PHINS III以及GPS接收机Trimble Marine SPS461与SAAB R5 SUPREME NAV作为导航传感器。原始数据从DAVIS SHIP数据库（https://dship.o2a-data.de）下载，时间分辨率为1秒。本数据集的处理与评估流程详见EPIC仓储中的数据处理报告，访问链接为https://hdl.handle.net/10013/epic.e4ce4177-53dc-4a00-a678-cecacd7a3de1。本次提供的处理后数据包含两类：一类是基于按优先级筛选的位置传感器数据生成、时间分辨率为1秒的主航迹；另一类是对主航迹中最具代表性的位置点进行精简后得到的概化航迹。
