Master track of HEINCKE cruise HE657 in 1 sec resolution (zipped, 12 MB)

Raw data acquired by position sensors on board RV Heincke during expedition HE657 were processed to receive a validated master track which can be used as reference of further expedition data. During HE657 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.

本数据集基于科考航次HE657期间，海因克号科考船（RV Heincke）所载位置传感器采集的原始数据处理得到，经校验的主航迹可作为后续科考航次数据的参考基准。本次航次HE657搭载的导航传感器包括IXSEA PHINS III惯性导航系统，以及Trimble Marine SPS461型与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。处理后的数据包含两类航迹产品：一类是依据优先级筛选位置传感器数据后生成的1秒分辨率主航迹；另一类是从主航迹中提取核心关键位置子集得到的简化概化航迹。
