The Deep Space Network was established by the National Aeronautics and Space Administration (NASA) and became a part of the Jet Propulsion Laboratory (JPL) of NASA. This is an international antenna network that supports interplanetary missions, radio communication, and observation and exploration of the solar system and the universe through radio astronomy. The network also supports some specific Earth orbit missions. It is the largest and most sensitive communication system for scientific research on earth.
At present, the deep space network consists of three deep space communication facilities, which are distributed at 120 degrees. One is located in GoldSi Tong, California, USA, in the Mojave Desert near Madrid; One is located near Madrid, Spain; The other is near Canberra, Australia. This arrangement makes continuous observation possible during the earth's rotation.
