SAS imparts radial in/out velocity on spacecraft - most noticeable around low-gravity bodies

  • CPU and GPU models: AMD Ryzen 9 3900XT |  nVidia Geforce RTX 3090 Founders
  • Description of the bug.  
    • Expected Behavior: Rotational maneuvers using SAS should not induce linear velocity changes in the spacecraft.
    • Observed Behavior: Rotational maneuvers using SAS impart significant linear velocity changes on the spacecraft in what appears to be the radial in/out directions (depending on direction of the rotation)
  • Steps to Replicate:  This is somewhat noticeable around any body, but is MOST noticeable around low-gravity bodies where orbital changes of >1km can be observed merely by rotating the craft 180 degrees or asking SAS to hold orientation for a period of time.
  • Fixes / Workarounds (if known..) : The only workaround I've found is to disable SAS as soon as the craft is stable in a given orientation, and if needed, use correction burns to adjust the orbit.
  • A list of ALL mods.  If the list is long, please consider using a spoiler window: NONE
