Python toolbox for managing and transforming GPS positions for measurements into a cartesian coordinate system anchored in drifting sea ice using a reference station. The toolbox was created for the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC), but can be used with any source of reference data.
The toolbox has built-in supports two source of reference sources:
1. Polarstern position and heading
2. MOSAiC floenavi virtual reference station
**Requirements**:
Zhe toolbox is based on python 3 and has been tested until python 3.7 version so far. In addition to standard python packages it uses the `icedrift <https://gitlab.awi.de/floenavi-crs/icedrift/>`_ package for the coordinate transformation.
**Installation**:
The python uses standard python package conventions and can be installed with pip directly from the git repository:
1. `floenavi basestation data <https://gitlab.awi.de/floenavi-crs/floenavi/-/blob/master/examples/mosaic-floenavi-example.ipynb?expanded=true&viewer=rich>`_
2. `polarstern reference data <https://gitlab.awi.de/floenavi-crs/floenavi/-/blob/master/examples/mosaic-polarstern-refstat-example.ipynb?expanded=true&viewer=rich>`_
