Master track of MARIA S. MERIAN cruise MSM129/2 in 1 sec resolution (zipped, 107 MB)

Raw data acquired by position sensors on board RV MERIAN during expedition MSM129/2 were processed to receive a validated master track which can be used as reference of further expedition data. During MSM129/2 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.

本数据集源自考察航次MSM129/2期间，搭载于‘梅里安号’（RV MERIAN）研究船的位置传感器所采集的原始数据，经处理后得到经验证的主航迹，可作为后续考察航次数据的参照基准。本次MSM129/2航次中，所用导航传感器包括Kongsberg SeaTex AS MRU-5型运动参考单元、Kongsberg SeaTex AS Seapath 320型设备，以及Trimble SPS855与SAAB R4型GPS接收机。数据以1秒的采样分辨率从DAVIS SHIP数据库（http://dship.bsh.de）下载获取。数据的处理与评估流程详见数据处理报告。本次提供的处理后数据包含两类航迹：一类为以1秒采样分辨率生成的主航迹，其基于按优先级筛选的位置传感器数据构建；另一类为简化航迹，通过从主航迹中选取最具代表性的位置点集进行精简得到。
