SuppressICRF
When set to false, the ICRF is used as the inertial reference frame for the Earth and the Sun for the purpose of trajectory generation and observation modeling. In this mode, transformations from the ICRF to the Earth fixed frame use the IAU 2000 combined theory of precession and nutation. Transformations between the ICRF and the MEME of J2000 frame are performed using the Earth pseudo-fixed frame (pole wander is not applied) as the intermediary frame.
When ICRF is the default inertial frame, ephemeris files from the simulator, filter and smoother will be written in this frame. These files will be stamped as stk.v.9.0 files and will only be readable by STK v9 and later. If you are creating ephemeris files for use in a version of STK prior to v9, set SuppressICRF to true.
