Master tracks in different resolutions of HEINCKE cruise HE625, Bremerhaven - Bremerhaven, 2023-06-29 - 2023-07-18

Raw data acquired by position sensors on board RV Heincke during expedition HE625 were processed to receive a validated master track which can be used as reference of further expedition data. During HE625 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.

本数据集由海因克号（RV Heincke）在HE625航次期间搭载的位置传感器采集的原始数据处理得到，经处理后生成经验证的主航迹，可作为后续航次数据的参考基准。HE625航次期间，所用导航传感器包括惯性导航系统（inertial navigation system）IXSEA PHINS III，以及GPS接收机Trimble Marine SPS461与SAAB R5 SUPREME NAV。原始数据从DAVIS SHIP数据库（https://dship.o2a-data.de）下载，其时间分辨率为1秒。本次发布的处理后数据包含两类：一类是基于按优先级遴选的位置传感器数据生成的1秒分辨率主航迹；另一类是对主航迹中关键位置进行精简后得到的概化航迹。
