Master tracks in different resolutions of MARIA S. MERIAN cruise MSM133, Las Palmas - Las Palmas, 2025-01-16 - 2025-01-30

Raw data acquired by position sensors on board RV MERIAN during expedition MSM133 were processed to receive a validated master track which can be used as reference of further expedition data. During MSM133 the motion reference unit Kongsberg SeaTex AS MRU-5 combined with Kongsberg SeaTex AS Seapath 320 and the GPS receivers Trimble SPS855 and SAAB R4 were used as navigation sensors. Data were downloaded from DAVIS SHIP data base (http://dship.bsh.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. 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

本数据集对MSM133科考航次期间，研究船梅利安号（RV MERIAN）搭载的位置传感器所采集的原始数据进行处理，得到经验证的主航迹（master track），可作为后续科考航次数据的参考基准。本次MSM133航次采用的导航传感器包括康斯贝格SeaTex AS MRU-5运动参考单元、康斯贝格SeaTex AS Seapath 320设备，以及Trimble SPS855与SAAB R4型GPS接收机。原始数据从DAVIS SHIP数据库（http://dship.bsh.de）下载，时间分辨率为1秒。数据的处理与评估流程详见配套的数据处理报告。本次处理后的数据包含两类成果：一类是基于优先级筛选的位置传感器数据生成的1秒分辨率主航迹；另一类是对主航迹中最具代表性的位置进行精简后得到的概化航迹。
