Master tracks in different resolutions of HEINCKE cruise HE665, Bremerhaven - Bremerhaven, 2025-07-26 - 2025-07-28

Raw data acquired by position sensors on board RV Heincke during expedition HE665 were processed to receive a validated master track which can be used as reference of further expedition data. During HE665 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.awi.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HE665航次期间船载位置传感器采集的原始数据处理生成，所得经过验证的主航迹可作为后续航次数据的参考基准。本次航次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。数据从DAVIS SHIP数据库（https://dship.awi.de）下载，原始分辨率为1秒。处理后的数据包含两类航迹：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；另一类为选取主航迹中最具代表性的位置点进行精简后得到的概略航迹。
