Kinematically corrected GNSS/INS buoy data during the MOSAiC expedition 2019-2020

This dataset contains the post-processed GNSS/INS buoy data for a kinematic correction of a moving base station. The GNSS/INS buoys were deployed on sea ice during the 2019-20 MOSAiC expedition. These buoys recorded raw GNSS/INS data at a sampling rate of 10 Hz. For the kinematic correction, two buoys (with overlapping measurements of each other) were selected, and one of the buoys was used as a moving "base" and the other as the "rover". The post-processed dataset contains kinematically corrected latitude, longitude and velocity of the rover, as well as the baseline distance between the rover and base. The main objective of the kinematic correction is to create high-precision and high-frequency data to measure ice dynamics at a few centimetre accuracies. The buoys were assembled by the University of Huddersfield team and the deployment was done by the MOSAiC ice team throughout the expedition.

This work was funded by NERC MOSAiC program NE/S002545/1.

Statement: The kinematic correction of the raw GNSS/INS data was conducted using Kinematica from Advanced Navigation (advancednavigation.com). The raw GNSS/INS data (in ANPP format) was converted to RINEX format for a kinematic correction with a moving base station. The processed data contain Moving Base Fix Type (i.e., the type of GNSS fix between the rover and the base station). For the data quality, the data with Fix Type* = 7 (i.e., RTK fixed - Carrier phase ambiguities have been resolved) were selected in this dataset.

Note that Leg5 data are not included in this dataset. No changes were observed in Leg5 and some errors were found during the data processing.

*Fix Type: Fix type 0 - No Fix; 1 - 2D; 2 - 3D fix (no base station data); 3 - SBAS; 4 - Differential (Base station data does not include carrier phase corrections); 5 - Omnistar; 6 - RTK Float (Carrier phase ambiguities cannot be resolved); 7 - RTK Fixed (Carrier phase ambiguities have been resolved).
