Master tracks in different resolutions of METEOR cruise M198, Catania - Catania, 2024-02-09 - 2024-02-22

Raw data acquired by position sensors on board RV METEOR during expedition M198 were processed to receive a validated master track which can be used as reference of further expedition data. During M198 the motion reference unit Kongsberg SeaTex AS MRU-5 combined with Kongsberg SeaTex AS Seapath 320 and two C and C Technologies GPS receivers C-NAV3050 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.

本数据集基于航次M198期间，研究船流星号（RV METEOR）搭载的位置传感器采集的原始数据处理得到，最终生成经过验证的主航迹，可作为后续航次数据的参考基准。本次航次M198所使用的导航传感器包括：康斯伯格SeaTex AS MRU-5型运动参考单元、康斯伯格SeaTex AS Seapath 320型系统，以及两台C&C科技（C and C Technologies）C-NAV3050型GPS接收机。相关原始数据从DAVIS SHIP数据库（http://dship.bsh.de）下载，采样分辨率为1秒。数据的处理与评估细节详见配套的数据处理报告。本次提供的处理后数据包含两类航迹：其一为按优先级筛选位置传感器数据后导出的1秒分辨率主航迹；其二为选取主航迹中最关键的位置点进行精简后得到的简化航迹。
