Control Satellite Attitude ?

[gardinwin]

Hi
I'd like to control attitude.
To change the satellite's attitude to Right Looking or Left Looking for mission operations, what command can be used to control it?

Thanks.

SC_Simle.txt contains :
*************************** Initial Attitude ***************************
13 NAN ! Ang Vel wrt [NL], Att [QA] wrt [NLEF]
14 0.3 0.4 0.5 ! Ang Vel (deg/sec)
15 0.0 0.0 0.0 1.0 ! Quaternion
16 20.0 30.0 40.0 213 ! Angles (deg) & Euler Sequence

Is it necessary to adjust the satellite to point directly downward toward the Earth?
