Queqiao Telecom Comprehensive Constellation System
Since one side of the moon always faces away from the earth, a probe landing on the back of the moon is blocked by the moon itself and cannot directly achieve measurement and control communication and data transmission with the earth. The landing detection and sampling sites for the fourth phase of the lunar exploration project are mainly located in the south pole and far side of the moon. Therefore, relay stars with wider functions and stronger performance are needed to set up a new "relay communication station" from the moon to the earth. , to solve the communication and data transmission problems between the probe on the back of the moon and the earth.
On the eighth China Space Day in 2023, the two Queqiao communication technology test satellites were officially named "Tiandu-1" and "Tiandu-2". The "Tiandu-1" satellite weighs 61 kilograms and is equipped with Ka dual-band integrated communication devices, laser corner reflectors, space routers and other loads.
鹊桥通导遥综合星座系统
由于月球始终有一面背对地球，着陆在月球背面的探测器受到月球自身的遮挡，无法直接实现与地球的测控通信和数据传输。而探月工程四期的任务开展着陆探测以及采样地点主要位于月球南极和月球背面地区，因此需要功能更广、性能更强的中继星，架设起月球对地新的“中继通信站”，解决月球背面探测器与地球间的通信和数传问题。
在2023年第八个中国航天日上，两颗鹊桥通导技术试验卫星正式被命名为“天都一号”“天都二号”。“天都一号”整星重量61千克，配置了Ka双频段一体化通信机、激光角反射器、空间路由器等载荷。
