When the spacecraft is in nadir pointing mode, the +Z axis points towards the centre of Venus and the +X axis is perpendicular to the ground track. Unlike Mars Express, the speed vector of the spacecraft can be tilted from the +Y axis direction at an angle a. The 3-tuple (x, y, z) defines the coordinates of the normalised spacecraft speed vector. As a consequence, we have:    x = sin a    y = cos a",
