The pointing control accuracy is better than 0.03 degrees, the solar cell array output power is greater than 1350 watts, equipped with a 135 Ah battery, communicates based on the S-band Unified Measurement and Control (Unified S Band) system and the Very Long Baseline Interferometry (VLBl) system, the uplink communication rate is 2000bps, the downlink communication rate 4096/512bps, the satellite mass is about 1.2 tons, contains 488 kilograms of propellant, and has a design life of more than 8 years.

The communication payload carried by the satellite includes a 4.2-meter-diameter X-band parabolic antenna, which is used to communicate with the detector without a tracking device and points to the detector through the guidance navigation and control system (GNC); a 0.6-meter-diameter S/Ka dual-band parabolic antenna, Used to transmit data to the ground station, dual-axis tracking and pointing to the ground station; S-band relay antenna for measurement and control (TT&C); ultra-high frequency (UHF) relay antenna. In addition to providing data and signal forwarding, “Queqiao 2” will also forward various ground uplink instructions to the detector. At the same time, “Queqiao 2” is also a scientific exploration satellite equipped with an extreme ultraviolet camera, an array neutral atom imager, and the Earth-Moon Very Long Baseline Interferometry (VLBl) system.



Subsequently, with the support of ground measurement and control, Queqiao-2 will enter the capture orbit after mid-month correction and near-month braking; then enter the phase-modulation orbit after orbit control, and finally enter the 24-hour lunar mission orbit, becoming the successor to “Queqiao”. “After the relay star, it is the world’s second dedicated relay star beyond the earth’s orbit, providing support for the Chang’e-6 lunar sampling mission, and relaying the “Queqiao” relay star to provide relay communication services for Chang’e-4.

After the Long March 8 Yao-3 carrier rocket flew for 24 minutes, the star and arrow separated, sending the Queqiao-2 relay satellite directly into the predetermined Earth-moon transfer orbit with a perigee altitude of 200 kilometers and an apogee altitude of 420,000 kilometers. The relay star’s solar wing and center The communication antennas were deployed normally one after another. Subsequently, with the support of ground measurement and control, Queqiao-2 will enter the capture orbit after mid-month correction and near-month braking; then enter the phase-modulation orbit after orbit control, and finally enter the 24-hour lunar mission orbit, becoming the successor to “Queqiao”. “After the relay star, it is the world’s second dedicated relay star beyond the earth’s orbit, providing support for the Chang’e-6 lunar sampling mission, and relaying the “Queqiao” relay satellite to provide relay communication services for Chang’e-4.

Queqiao-2″ relay satellite and the carrying satellites “Tiandu-1” and “Tiandu-2” communication technology test satellites. The Long March 8 Yao-3 carrier rocket will be launched from Station 201 of the Wenchang launch site and will send the satellite into the Earth-moon transfer orbit. Minus 45 minutes after launch, the three-story rotating platform has all been opened.
