Austria's DORF TV looks at how radio amateur Reinhard Kühn DK5LA from Sörup, Schleswig-Holstein, become a team member of the Chinese Longjiang-2 lunar mission?
After the introductory words on the Chinese lunar mission, Reinhard Kühn will introduce us to his radio station DK5LA. This lecture explains the radio connection from Earth to the moon and returns using sent and rereceived voice messages.
In addition to the presentation of the tasks that the satellite "Longjiang-2" had, he introduces us to the commands and satellite telemetry and describes the tasks of the "uplink" or "downlink" stations. The mission was crowned, among other things, by the sensational photos of a solar eclipse from the satellite in lunar orbit.
The first connection via a satellite in lunar orbit opened up a new dimension that has made radio history. The last radio command at the end of "Longjiang-2" came from Sörup. This command was important for determining the impact point on the back of the moon.
