AVT is
an ADS Package
1 surveillance system validation tool.
Shadow mode exercises with either live or simulated targets are
supported. The testbed conforms to the ADS-B
and TIS-B Surveillance System Architecture proposed by the EUROCONTROL ADS Programme, supporting multiple
ADS-B link technologies, ADS-B and radar track fusion, TIS-B uplinks, and the
use of ASTERIX
standards for surveillance data distribution.
AVT is being
developed in three consecutive phases and uses off-the-shelf components where
possible. ARTAS is
used as the surveillance data processing system, and ESCAPE
provides controller working positions and tools. AVT also includes aircraft
simulators providing cockpit displays and datalink error models injecting
errors in simulated surveillance data.
. AVT Phase 1 was completed in January 2003 with a demonstration in
Malmö ATCC, Sweden, using live VDL-4 equipped aircraft and multiple Swedish
radars. This demonstration was organised in collaboration with the Swedish Civil Aviation Administration
and AerotechTelub
(which contributed an additional CWP: i-acs Integrated Air Traffic Control Systems).
The demo report and presentations can be obtained from the Eurocontrol
ADS Programme web page
AVT Phase 2
development is in progress and will provide more advanced techniques for ADS-B
and radar track fusion and a second technology for ADS-B besides VDL-4. Phase 2 is scheduled for completion in the
third quarter of 2003. AVT Phase 3 will follow to provide TIS-B services and
support for a third ADS-B technology. Phase 3 is scheduled to complete in the
second quarter of 2004.
