Where Performance Matters

Datalink and airport solutions


The use of digital communications technologies has become an essential aspect of optimizing air traffic management and increasing airspace capacity. We ensure the top performance of current datalink avionics and ground systems, and we help to prepare the air traffic management system for the installation of future technologies.


Airports are seeing an increased demand for traffic, creating delays and bottlenecks both on the surface and in the skies. Our solutions provide real-time visibility over airport traffic, automated detection of operational milestones and resources monitoring and scheduling, for increased safety and efficiency levels.


ALTYS is actively involved in research projects both in Europe and internationally, and we are proud to invest 20% of our annual revenue into R&D. We have played a key role in a number of R&D projects as part of global air traffic management modernization initiatives such as SESAR Joint Undertaking.







At ALTYS, we are passionate about finding innovative ways to apply new digital technologies to the airport and air traffic management industries.

We are committed to a data-driven future – yet we have a deep understanding of the long-established trends of the world of civil aviation.

Our force comes from our ambition, our creativity, and our unique position at the crossroads of aviation and digital technology.

Leveraging the power of the skies’ big data

The ADELIS solution, delivered by ALTYS Technologies, is an integral part of our new Amsterdam Data Center. The infrastructure has added an extra layer of resilience to SITA’s ATN service.

ALTYS also provided us with the tools during infrastructure testing, which allowed us to simulate diverse operational scenarios to increase the fidelity of our testing.

The technical support provided by ALTYS throughout the project has helped us make service improvements an operational reality.
