TopSky
# TopSky

The TopSky (formerly EUROCAT) system is a computerised air traffic control and management solution developed by Thales Air Systems (formerly Thomson CSF). It utilises a distributed computing architecture and is capable of integrating geographically dispersed air traffic control units within a Flight Information Region (e.g. control towers at different airports and en route control centres) into a single coherent system.

During 2012, the Thales marketing name has been changed from Eurocat to TopSky.
