Master track of HEINCKE cruise HE601 in 1 sec resolution (zipped, 2.9 MB)

Raw data acquired by position sensors on board RV Heincke during expedition HE601 were processed to receive a validated master track which can be used as reference of further expedition data. During HE601 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.

本数据集基于HE601航次期间，研究船海因克号（RV Heincke）搭载的位置传感器采集的原始数据处理生成，经验证的主航迹可作为后续航次数据的参考基准。HE601航次所使用的导航传感器包括IXSEA PHINS III型惯性导航系统，以及Trimble Marine SPS461与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，采样分辨率为1秒。本次提供的处理后数据包含两类：一类是按优先级筛选位置传感器数据后生成、采样分辨率为1秒的主航迹；另一类是从主航迹中选取关键位置点进行精简得到的概略航迹。
