ALS ATC System

Comprehensive and Extremely Flexible ATM Solution

ALS features a unique concept of parametrization which makes this solution easily adaptable to your specific operational needs. Our team of ATC experts is ready to tailor the system according to your local situation and habits and with aim to maximize comfort for your ATCOs.

All data (radar and non-radar)
accessible from both Controllers´
Both ATCOs – EC and PLCcan access the same functionalities. This results in better substitutability and operational safety.
Degradation resistant CWS CWS takes over a number of server functionalities, which makes CWS more independent. This allows CWS to operate also in case of server overload.
Complex position information ALS provides a well organized and visually distinctive display of position information of all types (flight plan, ADS-C, radar tracking). This feature steps forward to fully stripless system.
Seamless Controller-Pilot and
Controller-Controller communication
Datalink CPDLC is integrated into ALS system and can be controlled by ATCO from CWS HMI. SYSCO is offered as a part of OLDI.
Wide range of non-radar data
presentation options
Presentation of non radar data kinds (paper, strips, glass, electronic) can be adjusted and customized according to your local settings. All electronic strip data are editable and ready to be shared.
Safety Nets, Monitoring Aids and
These warning modules are offered as an integral part of ALS with expert setting and fine-tuning assistance.
Easy adjustments due to high level
of parameterization
ALS can be easily tailored to ATCO specific needs, such as HMI colors and control, e-strip layout, strip posting rules, Safety Nets etc.
Billing and Statistics module Adjustable in accordance with your local billing rules.
Data Security In case of CWS failure, key data and functions are available at Supervisor´s position.
Record and replay feature ALS allows recording and replay all operational dataincluding audio communication. Record can be used for the evaluation of emergency situation.
HW redundancy and seamless
ALS has been developed with regards to performance redundancy and full hardware redundancy. ALS switching feature guarantees uninterrupted system operation.
Advanced CWS sectorization ALS operates with the feature of quick and safe sector redistribution in case of CWS outage. The sectors of any CWS can be seamlessly transferred to any other CWS.


  • Software development strictly follows ISO/IEC 12207 normative. 
  • Functional Hazard Assessment is used as the basis for System design.
  • PSSA is a component part of ALS product.
Open architecture ALS open architecture allows tailor-made solutions which may be gradually developed and changed according to your operating needs.
Distributed system ALS deploys distributed computing between the core and applied modules which makes the whole system more degradation resistant. For example, CWS takes over a number of server functionalities and consequently reduces the load of its operations.

Reliability and Robustness High availability and reliability of the system is supported by hardware redundancy and quick software switching.
Customizable AIS module All necessary data for Flight information service (AIS, MET, warning frequencies, etc.) can be displayed on a separate screen or in a window on CWS display (depending on custom settings).
Surveillance data flexibility
presentation options
Module Tracker processes Radar, Passive radar and ADS-C data. The most accurate data available are chosen for position computing. In case of an absence of surveillance data (in areas with no radar coverage), the CWS screen displays Flight Plan Tracks computed by FDPS.
Easy setting of interoperability Interoperability is defined in custom “Data Set” meaning it can be quickly adapted to local coordination adjusting and transfer conditions.
Sophisticated two-way
AFTN module
The AFTN Daemon does not only process incoming AFTN messages, but enables you to compile and distribute all kinds of AFTN messages as well.
Comprehensive monitoring and
The Monitoring module is an integral part of the whole system. It continuously generates the overview of the status and possible errors of individual ALS components. Early warnings enable to eliminate significant malfunctions.
OLDI complying with Eurocontrol
The module is an integral part of ALS and is adjustable to your local needs. It can be also deactivated.
4D Trajectory Prediction
ALS features cutting-edge functionalities. 4D Trajectory Prediction is driven by advanced route extraction operating within AoI (Area of Interest). The ETO and altitude computation are enhanced by radar updating and the results are based on complex computing using the instant aircraft propulsive performance as one of the parameters. This results in exact altitude attitude prediction.
Datalink for uncovered areas ALS is able to use Datalink functionalities (such as CPDLC and ADS-C) for oceanic sectors or areas without radar and radio coverage.



ALS Tracker

Multitracker system handles all kinds of surveillance data sources (even modern ones such as multilateration and ADS-B/C). Deploys advanced tracking procedures and creates consolidated, real-time air situation picture. Due to its efficiency, interoperability, and minimal HW requirements, it can be applied in systems requiring maximum performance and quick response.


ALS CWS / Ground CWS

ALS CWS / Ground CWS provides controllers with a clearly structured display of the air traffic/ground situation integrating the surveillance data and the flight data. The position data are received from the tracker and displayed in the main and the secondary radar window, together with other aircraft information on a background of colour maps of Area of Interest (AoI). The flight plans are received from Flight Data Processing System (FDPS) and displayed as fully customizable electronic strips. ALS CWS automatically matches the flight plans to the tracks.
