Clocks on the shady side: Meanwhile the base of the satellite – covered with reflective panels – is intended to be always kept out of sunlight and in shadow. On the inside of this panel is where Galileo’s four clocks are mounted. The aim to keep their operating temperatures stable to within 0.5 °C, to a maximum 20°C, when the difference between the sunny and shaded side of the satellite surface is more than 200°C. The latest ‘Batch 3’ Galileo atomic clocks are protected with an additional radiation shielding on the satellite to further boost their stability.
