Transmission time per day for Chang'e 4?












3














Congratulations for the sucessfull landing on the back side of the Moon.



There is continuous radio connection from the lander to the Queqiao relay satellite at the Earth-Moon L2 point. But what about the transmission from the relay satellite to ground stations on Earth? Are there antennas on Chinese territory only or is there a global Chinese system, like the DSN system?

          Right now, the Chinese Deep Space Network is only in China, although there are a number of locations there. They are building a station in South America, however, which should give near continuous communication. The setup they have should allow for roughly 16 hours/ day of communication to any deep space object, including Queqiao.



          Note that the Wikipedia article seems to be out of date, the South American station is now operational. As a result, there should be 24 hours/ day possible, during the lunar day.

            According to this article, the station in south America began operation in march 2018. So about 24 hours/day should be possible.
