INT_AUR 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.
INT_AUR Q1=U*sin(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.
INT_AUR Q2 = V*sin(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.
INT_AUR Q3 = W*sin(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.
