Shiyan-20C, completing the three-satellite Shiyan-20 formation. Together the trio's coordinated 60°-inclination orbit and simultaneous 2022 launch suggest a deliberately designed group mission, though — as with much of China's Shiyan program — the specific technology being tested has not been publicly detailed.
