Madrid Deep Space Communication Complex
Welcome to our website. It is generaly simplier version of wikipedia. You will find there selected articles. Enjoy!
The Madrid Deep Space Communications Complex (MDSCC) is a ground station located in Robledo de Chavela, Spain, and operated by Ingenieria y Servicios Aeroespaciales, S.A. (INSA) for Instituto Nacional de Técnica Aeroespacial.

Deep Space Network
It is part of NASA's Deep Space Network run by the Jet Propulsion Laboratory. The facility contributes to the Deep Space Network's ability to provide the vital two-way communications link that guides and controls remote control drones and receives the images and new scientific information they collect. This complex is one of three NASA Deep Space Network complexes in the world; the others are the Goldstone Deep Space Communications Complex located in California, near the city of Barstow, and the Canberra Deep Space Communication Complex in Australia which is close to the city of Canberra.
Functions
The antennas and data delivery systems make it possible to:
- Acquire telemetry data from spacecraft.
- Transmit commands to spacecraft.
- Track spacecraft position and velocity.
- Perform Radio Astronomy (both single-dish and very-long-baseline interferometry) observations.
- Measure variations in radio waves for radio science experiments.
- Monitor and control the performance of the Deep Space Network.
Antennas
The complex has five antennas, called DSS-54, DSS-55, DSS-63, DSS-65 and DSS-66 .
- DSS-54 and DSS-55 are 34-meter beam waveguide (BWG) antennas.
- DSS-63 was built in 1974 as a 64-meter antenna, and upgraded to 70 metres in the late 1980s. It can transmit in S and X-band with a power up to 400 kilowatts and receive in L, S, and X bands. DSS-63 weighs a total of 8000 tons, whereby the dish has a weight of 3500 tons. Its reflecting surface is 4180 m2.
- DSS-65 was built in 1987 and has a diameter of 34 meters. It is a HEF (high-efficiency) antenna. It can transmit in X-band with a maximum power of 20 kW and receive in S- and X-band. The weight of DSS-65 is 400 tons, whereby the dish weighs 350 tons.
- DSS-66 is a 26-meter antenna used in support of near-Earth missions and the early orbit phase of deep-space missions. This antenna was moved from the nearby NASA tracking station at Fresnedillas in 1983.
