The Deep Space Exploration Laboratory released news on April 13 that as of the 12th, the Tiandu-1 and Tiandu-2 communication technology test satellites had successfully carried out high-reliability transmission and routing of the moon and the earth, and lunar orbit navigation space benchmark allogeneic calibration. Waiting for new technology trials. Calculation results based on telemetry data show that the test project can effectively improve the accuracy of spacecraft orbit determination around the moon, and the test design has important practical value.
After Tiandu-1 and Tiandu-2 were launched on March 20, after about 14 days of space flight, including mid-course correction, near-month braking, and orbital maneuvering around the moon, the double-star combination was launched on April 3. Successful separation of binary stars in mission orbit around the moon.
中國深空探測實驗室4月13日釋出消息稱，截至12日，天都一号、二号通導技術試驗星順利開展了月地高可靠傳輸與路由、月球軌道導航空間基準異源标定等新技術試驗。經遙測資料計算結果表明，試驗項目能夠有效提高航天器環月軌道定軌精度，試驗設計具有重要實用價值。
天都一号、二号自3月20日發射升空後，經中途修正、近月制動、環月軌道機動等關鍵環節，曆經約14天的太空飛行，雙星組合體于4月3日在環月使命軌道成功實施雙星分離。

On April 8, Tiandu-1 completed the flight orbit adjustment control as planned, and flew in formation with Tiandu-2 in a frozen orbit around the moon, with the distance between the two stars maintained at around 200 kilometers. The communication between the two satellites is normal, the posture is stable, and the energy is balanced, laying an important foundation for carrying out a series of communication technology test tasks.

4月8日，天都一号按計劃完成飛行軌道調整控制，與天都二号在環月大橢圓當機軌道編隊飛行，雙星距離維持在200公裡附近。兩星通信正常、姿态穩定、能源平衡，為開展系列通導技術試驗任務奠定重要基礎。
On April 8, 2024, Tiandu-2 took a photo of the Earth and the Moon. Moon imaging data in the far-infrared spectrum with a wavelength of 8~14 um. The smaller celestial body in the background is the Earth.
Tiandu 1 and 2, as the first satellites developed by the Deep Space Exploration Laboratory, carried out a series of new lunar communication and navigation tests, effectively verifying the key technologies related to lunar communication, and will provide the basis for the subsequent International Lunar Research Station and Queqiao Communication Provide strong support for the design and construction of remote integrated constellation systems.

天都一号、二号作為深空探測實驗室抓總研制的首發星，開展系列月球通信導航新技術試驗，有效驗證了月球通導相關關鍵技術，将為後續國際月球科研站、鵲橋通導遙綜合星座系統的設計建設提供有力支撐。
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.
鵲橋通導遙綜合星座系統
由于月球始終有一面背對地球，着陸在月球背面的探測器受到月球自身的遮擋，無法直接實作與地球的測控通信和資料傳輸。而探月工程四期的任務開展着陸探測以及采樣地點主要位于月球南極和月球背面地區，是以需要功能更廣、性能更強的中繼星，架設起月球對地新的“中繼通信站”，解決月球背面探測器與地球間的通信和數傳問題。
在2023年第八個中國航天日上，兩顆鵲橋通導技術試驗衛星正式被命名為“天都一号”“天都二号”。“天都一号”整星重量61千克，配置了Ka雙頻段一體化通信機、雷射角反射器、空間路由器等載荷。

According to the planned goals, after the two stars "Tiandu 1" and "Tiandu 2" entered the earth-moon transfer orbit together with the Queqiao 2 lunar relay satellite, the two stars performed near-month braking and entered a large elliptical orbit around the moon. , in a large elliptical orbit around the moon, using satellite-to-ground laser ranging, inter-satellite microwave ranging and other methods to carry out high-precision lunar orbit determination technology verification.
The Deep Space Exploration Laboratory is a new technology research and development institution jointly established by the National Space Administration, Anhui Province, and the University of Science and Technology of China. Chen xiao, commander-in-chief of Tiandu Navigation Technology Experimental Satellite of the Deep Space Exploration Laboratory, said that these two small and micro test satellites will provide strong reference and basis for the subsequent establishment of China's Queqiao Navigation and Telecommunications Comprehensive Constellation System.
