Master track of HEINCKE cruise HE593 in 1 sec resolution (zipped, 1.5 MB)

Raw data acquired by position sensors on board RV Heincke during expedition HE593 were processed to receive a validated master track which can be used as reference of further expedition data. During HE593 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.794dcceb-6596-401d-9858-455b63940c50. 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.

本数据集针对HE593科考航次期间，RV Heincke号研究船所搭载的位置传感器采集的原始数据进行处理，最终生成经过验证的主航迹（master track），可作为后续科考航次数据的参考依据。本次HE593航次所用的导航传感器包括IXSEA PHINS III型惯性导航系统，以及Trimble Marine SPS461、SAAB R5 SUPREME NAV型GPS接收机。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。该数据的处理与评估流程详见EPIC数据仓储（EPIC repository）中收录的数据处理报告，链接为https://hdl.handle.net/10013/epic.794dcceb-6596-401d-9858-455b63940c50。本数据集提供两类处理后的数据：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的关键位置进行精简后得到的概化航迹。
