The relay satellite took on the role of a data bridge, with Reconnaissance Star transmitting all data back to it for storage and signal modulation.
The relay satellite then sends the modulated signal back to the ground, received by the Yagi Antenna on Ban Xia's rooftop.
After the Yagi Antenna receives the signal, it is transmitted to the 725 amateur radio station, which then sends the data back to modern times.
The signal returned to the year 2019 is stored in multiple backups and simultaneously decoded—if the decoding is successful and results in a clear, identifiable photo, then the test is successful.
What would be the subject of the photo used for the test?
Everyone, without prior agreement or discussion, chose No. 66 on Muxuyuan Street in Qinhuai District.
Meihua Villa.
The first photo transmitted back from twenty years in the future, used to test the entire system, is a high-altitude overhead view of Meihua Villa during the doomsday period.
