Scientific paper

The conduction of space missions in the interplanetary space presents special communications problems in connection with the requirement to transmit signals to spacecraft in deep space over distances of a billion kilometers and to receive signals from these spacecraft. The solution of these problems requires the employment of huge parabolic reflectors as antennas in ground stations. Transmitters of high performance and receiving amplifiers with very low noise levels are needed. It is very desirable that the communication between spacecraft and earth should be maintained without interruption. In order to satisfy these conditions, the U.S. Deep Space Network maintains ground stations at Goldstone in California, Madrid in Spain, and Tidbinbilla in Australia. Parabolic antennas with a diameter of 26 m were initially used. These antennas have now been replaced by 64-m reflectors which provide a much more powerful signal. Attention is given to the station in Madrid, the 2100-MHz band employed, the receiver characteristics, the antennas, the spacecraft communication systems, and a number of space missions.
