Master tracks in different resolutions of HEINCKE cruise HE618, Bremerhaven - Bremerhaven, 2023-04-25 - 2023-05-07

Raw data acquired by position sensors on board RV Heincke during expedition HE618 were processed to receive a validated master track which can be used as reference of further expedition data. During HE618 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HE618航次期间科考船海因克号（RV Heincke）搭载的位置传感器采集的原始数据，经处理后生成经验证的主航迹（master track），可作为后续航次数据的参考基准。本次HE618航次所使用的导航传感器包含惯性导航系统IXSEA PHINS III，以及GPS接收机Trimble Marine SPS461与SAAB R5 SUPREME NAV。数据从DAVIS SHIP数据库（https://dship.o2a-data.de）下载，原始采样分辨率为1秒。处理后的数据分为两类：一类为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；另一类为精简主航迹中核心位置点得到的概化航迹。
