Master tracks in different resolutions of HEINCKE cruise HE552, 2020-07-19 - 2020-07-25

Raw data acquired by position sensors on board RV Heincke during expedition HE552 were processed to receive a validated master track which can be used as reference of further expedition data. Position sensors used during HE552 were the internal navigation system IXSEA PHINS III and the GPS receivers Trimble Marine SPS461 and SAAB R5 SUPREME NAV. 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 hdl:10013/epic.e0df8912-61ee-4512-8de8-8c2210ba8a98. 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.

本数据集针对海因克号研究船（RV Heincke）HE552航次期间搭载的位置传感器所采集的原始数据进行处理，以生成经验证的主航迹（master track），该航迹可作为后续航次数据的参考基准。本次HE552航次所使用的位置传感器包括内置导航系统IXSEA PHINS III，以及Trimble Marine SPS461和SAAB R5 SUPREME NAV型GPS接收机。原始数据以1秒的分辨率从DAVIS SHIP数据库（https://dship.o2a-data.de）下载获取。本数据集的处理与评估流程详见EPIC仓储（EPIC repository）中编号为hdl:10013/epic.e0df8912-61ee-4512-8de8-8c2210ba8a98的数据处理报告。处理后的数据包含两类：一类是基于优先级筛选的位置传感器数据生成的、分辨率为1秒的主航迹；另一类是对主航迹中关键位置进行精简后得到的概化航迹（generalized track）。
