Both modules are creating a control torque onto the spacecraft. You might be seeing RW saturation issues with the RW effector? |

I'm just guessing it could be related to RW saturations. I don't know for sure of course. I would recommend recording the module output messages, reading the module documentation, looking at the RW data that is being setup (see simIncludeRW.py utility file), etc. The attitude control module will create the same control torque in both cases, but something is different in the applied torques. |

@schaubh Hello Professor,
I want to achieve observation of one satellite A on another satellite B, where A and B are in different orbits.When I use the module 'extForceTorque' as an external control force, A star can accurately observe B star; But when I use the module 'ReactionWheelStateEffectiveness' as the control force, there is a deviation in the position of star A when observing star B, but I did not make any other changes. May I ask why this is?
