China has become a leader in the
cutting-edge technology of space-based, high-speed information transmission
thanks to an advanced satellite, according to the National Space
Administration.
The Shijian 13 communication satellite has
conducted the world's first experiment on high-orbit laser communication, a
technology crucial to enabling a spacecraft to send, receive and transmit a large
quantity of data with ground stations, the administration said in a statement
on Tuesday.
The experiment proved that the satellite is
capable of carrying out steady, high-speed and high-quality transmission of
information with the ground.
The fastest transmission speed recorded
during the experiment was five gigabytes of data per second, which means a user
could download a high-resolution movie within one second.
