Overview
--------
``OpNavScenarios/models/BSK_OpNavFsw.py`` contains the FSW algorithms used in the scenarios. Examples are the
Orbit Determination
filters, the pointing guidance module, the CNN module, and more. This file also contains the ``modeRequest`` definitions which
enable all the tasks necessary to perform a specific action.
