During MSM-X23 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 (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.This transit cruise was conducted without a designated chief scientist or scientist on board. However, "Underway" Research Data were recorded along the cruise track. Therefore, Susanne Tamm, Head of the German Oceanographic Data Center at the Federal Maritime and Hydrographic Agency of Germany (BSH), has been assigned as the author and contact person for this master track.-51.721108-15.41752128.13913464.169278Bundesministerium 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
