Whether travelling near Earth or deep in our Solar System, every spacecraft is supported by a sophisticated 'ground segment' comprising computer systems, software, telecommunication networks and other resources that enable engineers and scientists to send up commands and receive data from on board instruments.

ESA's Ground Systems Engineering team at ESOC comprises specialists who establish ground segments for satellite missions. We design, build and maintain deep-space tracking stations; provide flight dynamics, navigation and mission-analysis services; and we develop some of Europe’s best mission control software – now in use by industries as diverse as air traffic control and energy distribution.
