During MSM144 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 Insightics Marine DSHIP Extraction (https://dship.o2a-data.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.-21.942175-21.94200264.15411164.154221Bundesministerium für ­Forschung, Technologie und Raumfahrthttps://doi.org/10.13039/50110000234703F1001EAuf- und Ausbau Dateninfrastruktur und -management für Daten aus dem Betrieb deutscher Forschungsschiffe; Vorhaben: Bathymetrie-, Sedimentecholot-, Seismik- sowie weitere Unterwegs- und Forschungsmissionsdaten
