/* DATA DESCRIPTION: Citation: Isbert, Wolf (2026): Master tracks in different resolutions of HEINCKE cruise HE686/2, Bremerhaven - Bremerhaven, 2026-06-15 - 2026-06-16 [dataset]. Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven, PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.995864 (DOI registration in progress) Abstract: Raw data acquired by position sensors on board RV Heincke during expedition HE686_2 were processed to receive a validated master track which can be used as reference of further expedition data. During HE686_2 the inertial navigation system IXSEA PHINS III and the GPS receivers Trimble Marine SPS461 and SAAB R5 SUPREME NAV were used as navigation sensors. Data were downloaded from DAVIS SHIP data base (https://dship.o2a-data.de/) with a resolution of 1 sec. 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.
