The satellite data in simple.czml is defined in ICRF, so that’s the way it gets drawn. On the STK Components side, you want to add the [CesiumReferenceFrameExtension](https://www.agi.com/resources/help/online/agicomponents/html/T_AGI_Foundation_Cesium_CesiumReferenceFrameExtension.htm) to your Satellite and tell it to use ICRF frame. (I forget the exact code offhand, but it should be a one-liner. If you are still having problems let me know and I’ll post it when I’m back in the office.
