DLR (CC-BY 3.0).
In order to be able to communicate with a spacecraft, antenna systems are needed, DLR's ground Station in Weilheim, 60 kilometers southwest of Munich, was established in 1969 (start of construction November 1967) and is operated by the German Aerospace Center (GSOC). The data Exchange takes place via a variety of different antennas (ranging from 4.5 m up to 30 m diameter). The ground station is connected with GSOC through a redundant communication link. The control center in Oberpfaffenhofen coordinates the antenna operations and transmits the commandos which are generated in the controll room directly to Weilheim. In the opposite direction the data received from the spacecraft (telemetry, ranging-, Doppler and angle-data for orbit determination) is transmitted in digital form to the control center after it has been processed.
The individual antenna stations can be operated independently, which means Weilheim supports several missions simultaneoulsy. Also other space agencies or commercial operators regularly lease "antenna time" for their missions. Therefore Weilheim is embedded in a worldwide communication network. For this, several interfaces and protocols have to be implemented. In addition, antennas, facilities and systems have to be planned, configured and serviced. All antennas and station facilities are monitored and controlled from one common control room. For this, a software newly developed at GSOC is used that allows to standardize the necessary prodedures independent from the particular frequencies ranges and orbit types. Also the coordination of such a worldwide communication network is done at GSOC. In 24/7 operations, all the required data-links between the satellite control center and the ground station in use at a given time are established, configured and monitored.
Weilheim is classified as Deep Space Network as well as Non Deep Space Network (Near Earth Network) according to CCSDS (Consultative Committee for Space Data Systems) and is able to support space flight missions in the S-, X-, Ku and Ka frequency bands.
