Abstract
This chapter describes the design aspects of a typical Mission Control Center (MCC) and the Ground Station Network. The Mission Control Center—as the name implies—is the central ground facility of a space mission. It is the central point where all data and management information concerning the spacecraft are consolidated. These data are received, checked, and processed, decisions are made and—in case of an emergency—the respective procedures are performed in order to restore the nominal conditions of the mission. The way how the MCC operates is defined by its design which specifies its capabilities, flexibility, and robustness.
Within this chapter we focus on several aspects of the design of a control center. At first the necessary infrastructure is analyzed. Then the design of the local control center network is examined followed by the software needed.
The Ground Station Network (GSN) plays a major role in space missions. It has to establish communication with the spacecraft and with other control centers, support specific spacecraft characteristics, and provide operability and safety of the mission. Due to its nature, the GSN takes part in cross-support activities between different organizations and agencies. The GSN covers several functional aspects—the communication path between control center and the ground stations (transporting online data, off-line data, voice), the management of the stations and their antennas, as well as coordination tasks and station scheduling.
