It is dedicated to the mathematician Giuseppe Colombo and is focused on Earth observation (geodesy and satellite telemetry), space robotics and interplanetary missions.
The centre was created in 1983 by CNR, Region Basilicata and NASA and is managed by Telespazio. It was initially focused on Earth observation only. Today it has about 100 employees and is used for research activities and operational services such as data acquisition from a number of European satellites and ground segment of the COSMO-SkyMed satellite constellation.
