Queqiao-2’s 24-hour-period elliptical frozen orbit will place the satellite beyond the moon to provide line of sight with both Earth ground stations and Chang’e-6 in Apollo crater.
Queqiao-2 will use X-band and UHF frequencies to communicate with spacecraft and S-band and Ka-band frequencies to communicate with Earth.
Queqiao-2 will assist the ongoing Chang’e-4 lunar far side lander and rover after completing short-term support for Chang’e-6.
Queqiao-2 will launch with two experimental CubeSats named Tiandu-1 and Tiandu-2 to test lunar communications and navigation payloads.
Queqiao-2 will operate in a 24-hour-period inclined elliptical frozen orbit during support for Chang’e-6.
Queqiao-2 will switch to a 12-hour-period orbit to support the Chang’e-7 mission in 2026 and the Chang’e-8 mission in 2028.
Queqiao-2 is scheduled to launch in March 2024.
A relay satellite named Queqiao-2 will be launched early in 2024 to provide communications support for Chang’e-6, Chang’e-7, and Chang’e-8.
Queqiao-2 and its two Tiandu companion satellites will form part of Queqiao version 1.0 to establish Earth–moon communication capabilities.
Queqiao V2 would seek to provide whole-moon coverage with a proposed topology of three satellites each in EML1 and EML2, one satellite at EML3, six circular-orbit satellites, a pair in elliptical frozen orbits and a geostationary orbital interplanetary station.
Queqiao-2 is scheduled to launch around May next year to support the Chang’e-6, Chang’e-7 and Chang’e-8 far side and lunar south pole landing missions.
The Queqiao-2 relay satellite to support Chang’e-6 is scheduled to launch in March 2024.
Queqiao-2 will enter a distant retrograde orbit or an inclined highly elliptical frozen orbit to support Chang'e-6 rather than a halo orbit around Earth-Moon Lagrange point 2.
The first Queqiao satellite supported the 2019 Chang'e-4 mission, which achieved the first soft landing on the lunar far side.
Harbin Institute of Technology previously developed the Longjiang-1 and Longjiang-2 small satellites that piggybacked on the Queqiao lunar relay satellite to support the Chang’e-4 lunar far side landing mission.
Queqiao-2 will support the Chang’e-6 sample return mission scheduled to launch in May 2024.
Queqiao-2 is an upgraded relay satellite that will act as a communications relay for the Chang’e-7 and Chang’e-8 missions.
Queqiao-2 will launch in early 2024 to support upcoming robotic landing missions at the lunar south pole and the far side of the Moon.
Queqiao-2 will be an upgrade of the first Queqiao satellite that was launched in 2018 to the Earth–Moon L2 point to support the 2019 Chang’e-4 lunar far side lander and rover mission.
Queqiao-2 will likely change its orbit to an inclined, highly elliptical frozen orbit to provide communications coverage for Chang’e-7 and Chang’e-8.
