Master track of HEINCKE cruise HE666 in 1 sec resolution (zipped, 107 MB)

Raw data acquired by position sensors on board RV Heincke during expedition HE666 were processed to receive a validated master track which can be used as reference of further expedition data. During HE666 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HE666科考航次期间“海因克号”（RV Heincke）船载位置传感器采集的原始数据，经处理后得到经过验证的主航迹，可作为后续科考航次数据的参考基准。本次HE666航次采用的导航传感器包括惯性导航系统IXSEA PHINS III，以及Trimble Marine SPS461和SAAB R5 SUPREME NAV型GPS接收机。数据从DAVIS SHIP数据库（https://dship.o2a-data.de）下载，原始分辨率为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的1秒分辨率主航迹；另一类是对主航迹关键位置点进行精简后得到的概化航迹。
