Parameter #1
Name
INT_TAIL Q0 Attitude quaternion SC to GEI transformation
Description
INT_TAIL Q0 = cos(ALPHA/2) The attitude quaternion describes a transformation of a vector from spacecraft body coordinates into the GEI-1950 (Geocentric Equatorial Inertial) coordinate system. It represents a rotation of an ALPHA angle around an axis whose the unit vector coordinates are U, V, W.
