More information on the two Tiandu satellites that were launched alongside the Queqiao-2 (Magpie Bridge 2) relay satellite.

Both Tiandu satellites will be used to verify new space communication and navigation technologies. Tiandu-1 weighs 61kg and is equipped with a dual band (Ka/Ku?) communications device, a laser angle reflector, a router, etc. Tiandu-2 weighs 15kg and carryies a communications payload only. The two satellites will enter an elliptical orbit around the moon and carry out data transmission and data forwarding tests, as well as tests on a high-precision orbit determination system. These technologies are crucial for the future Magpie Bridge lunar constellation project, which will establish a Lunar-Earth communications and control network and a remote-sensing constellation orbiting the moon.

China has conducted the world's first daytime earth-moon laser ranging test. A laser beam was sent from a ground station to the Tiandu-1 satellite, which returned the beam back against the strong interference of daylight.
