Master track of HEINCKE cruise HE658 in 1 sec resolution (zipped, 44 MB)

Raw data acquired by position sensors on board RV Heincke during expedition HE658 were processed to receive a validated master track which can be used as reference of further expedition data. During HE658 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HE658航次期间海因克号（RV Heincke）搭载的位置传感器所采集的原始数据，经处理后生成经过验证的主航迹，可作为后续航次数据的参考基准。HE658航次所用的导航传感器包括IXSEA PHINS III惯性导航系统，以及Trimble Marine SPS461与SAAB R5 SUPREME NAV两款GPS接收机。数据从DAVIS SHIP数据库（https://dship.o2a-data.de）下载，原始数据分辨率为1秒。本次提供的处理后数据集包含两类航迹：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代表性位置点进行精简后得到的广义简化航迹。
