Euler Angles
The attitude of the vehicle (i.e., the rotation between the vehicle's body axes and the vehicle' central body's inertial frame) expressed using Euler angles. Euler angles use a sequence of three rotations starting from a reference coordinate frame. The rotations are performed in succession: each rotation is relative to the frame resulting from any previous rotations. The sequence of three rotations is indicated by a integer sequence where the X axis is 1, Y axis is 2, and Z axis is 3. For example, a 313 sequence uses Z, then the new X, and then finally the newest Z axis.Available for these objects: LaunchVehicle, Missile, Satellite
