Master tracks in different resolutions of HEINCKE cruise HE596, Bremerhaven - Bremerhaven, 2022-04-08 - 2022-04-13

Raw data acquired by position sensors on board RV Heincke during expedition HE596 were processed to receive a validated master track which can be used as reference of further expedition data. During HE596 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.

本次数据集的原始数据为海因克号研究船（RV Heincke）在HE596航次期间由其搭载的位置传感器采集所得，经处理后得到经过验证的主航迹（master track），可作为后续航次数据的参考基准。在HE596航次中，实验采用了惯性导航系统（inertial navigation system）IXSEA PHINS III，以及Trimble Marine SPS461和SAAB R5 SUPREME NAV型GPS接收机作为导航传感器。数据从DAVIS SHIP数据库（https://dship.o2a-data.de）下载，采样分辨率为1秒。本次提供的经处理数据包含两类航迹：一类为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；另一类为基于主航迹核心位置点精简生成的广义简化航迹。
