RapTOr: Remote Tower Operation with Augmented Vision Videopanorama Human System Interface



Remote Tower Operation (RTO) describes the goal of remote control of small airports and of movement areas of large airports which are not directly visible from the tower.

Project oview

The direct far view out of the tower windows should be replaced by an augmented vision video panorama. RapTOr (2005-2007) is the first step on the way to the RTO center for the control of multiple small airports and to the Virtual Tower (ViTo) control center for large airports as long term goal. The concept study „Virtual Tower“ (ViTo, 2002 - 2004) provided the starting point for RapTOr project. The results of RapTOr will be carried on in the project RAiCe (Remote Airport Traffic Control Center).

In 2005 the DLR project RapTOr was started in order to realize an RTO experimental system as extension of the Advanced Surface Movement Guidance and Control System (A-SMGCS) at the Braunschweig research airport. Analysis, cognitive modelling and simulation of the tower work procedures support the design and development of the demonstrator.

Research and development goals

1. Work analysis, modeling and simulation of operator decision making within the RTO augmented video panorama workplace environment in order to support the development process and the investigation of design alternatives.

2. Realization of an RTO – experimental environment and a demonstrator for augmented video panorama based remote airport control, including tests and concept validation with professional tower- / apron controllers.

Realization of the RTO experimental System

The direct view out of the tower windows is of central importance for surface traffic control under the present day working conditions of tower and apron controllers. That is why each attempt of surface movement management without direct view out of tower windows represents a revolution for tower controller working conditions.

Consequently it is assumed that under the guideline of human centered automation, the reconstruction of the direct far view in future A-SMGCS, in addition to the abstract (birds view) ground movement situation display showing the vehicle positions, will greatly improve the transition process to the new work environment and make it acceptable to the user. The design process for a RTO (and future ViTo) work environment relies on domain knowledge from experts (controllers) of the German Air Traffic Control Organisation (DFS), which provide the input data for the cognitive tower work analysis.

Demonstration and Results

The first life demonstration of the real – time high resolution 180° - video panorama reconstruction of Braunschweig research airport was realized at the occasion of the „5th ATM R&D Symposiums“ in Oktober 05 [http://atmsymposium.dlr.de]. It proved the possibility of real time tracking of moving aircraft e.g. during final approach and landing, with the PTZ camera.

Initial results of augmented vision by real time attachment to landing aircraft of transponder data with multilateration position was presented at the ICRAT 2006 conference in Belgrade [http://www.icrat.org].

 

The Institute of Flight Guidance presented the working console at the International Airshow ILA 2008 in Berlin. http://www.dlr.de/desktopdefault.aspx/tabid-4780/7926_read-12593/

Results of the RapTOr project were presented and discussed at the final workshop together with international experts in April 2008. The presentations and discussions focused on the topics: Virtual tower concept, work and task analysis, formal modeling and simulation of basic airport processes and decision making by using colored Petrinets, video reconstruction of the far view out of the tower windows, augmented vision, automatic movement detection, image processing and object tracking using a pan-tilt zoom camera, validation methodology, verification and initial validation of the video panorama system by means of flight testing, and an overview on the Swedish remote tower project ROT/ART.

The RapTOr results are published in a number of publications. Patents are applied for basic featurs of the RTO systems. The RTO console with augmented vision videopanorama display as human-system interface was on exhibit on several occasions, including the governments open doors day.

The follow-up project RAiCe (Remote Airport traffic control Center) continues the RapTOr project with the goal of develoing and testing a center work environment for the remote control of two small airports.
