On the 6th of November 2008, a contract was signed by Estonian ANS and AviBit data processing GmbH - an Austrian company - on procuring Tower ATM and Ground Movement Guidance and Control systems as part of Tallinn Tower Modernisation project.

Tallinn airport has rapidly developed making ground traffic management more complicated. To be able to meet the increasing demand Estonian ANS launched Tallinn Tower Modernisation project with an objective to enhance capacity at Tallinn aerodrome, increase ground traffic safety and improve quality of the services.

Within the frames of this project it is planned to upgrade the existing Air Traffic Management System and its supporting systems, to implement an on-line data exchange between Tallinn Airport, Approach Control Unit (APP) and other cooperation partners. The project also covers an update of Tower (TWR) work positions and operating methods, installation at Tallinn aerodrome ground movement surveillance system, i.e. radar and MLAT sensors including safety nets.
