Contributing to the next generation of ATM and CNS

ALTYS is actively involved in research projects both in the Air Traffic Management (ATM) and Communications, Navigation, and Surveillance (CNS) domains.
We are proud to invest 20% of our annual revenue into R&D.

Future CNS technologies

As part of the SANDRA project, we researched future concepts for avionics communication systems and airport datalink. ALTYS is also working to improve airport surveillance systems through the integration of video sensor technology, as well as with the use of 2nd-generation MLAT technology alongside our partner Japan Radio Co., Ltd. (JRC).
As members of EUROCAE and participants in the AEEC working group, we contribute to the evolution of communications and surveillance standards, including ATN/IPS, AeroMACS, LDACS, and Future SatCom, as well as next-generation surveillance systems.

Integrating all air traffic into the ATM system

In ongoing SESAR-backed efforts to expand the current ATM system to host all air traffic — including UAVs and general aviation traffic — ALTYS led the AGATHA project alongside ENAC (Ecole Nationale de l’Aviation Civile) and M3 Systems. The project proposed detailed technical recommendations to enable the smooth integration of General Aviation (GA) into the SESAR concept, taking into account the GA community’s specific cost, size and weight constraints.

Modeling Airspace

As part of efforts to ensure VDL Mode 2 system capacity in the U.S. prior to full deployment, ALTYS worked in collaboration with Harris Corporation in order to model the U.S. National Airspace System. ALTYS was also responsible for the development of a highly realistic model of European airspace as part of the SESAR ELSA Consortium, led by NATS. As a Work Area Leader of ELSA – alongside Airbus and ENAV – ALTYS was in charge of large-scale simulation and airport equipment testing in realistic RF conditions.

Trajectory prediction & optimization

ALTYS is active in the STARGATE project, whose objective is to dynamically plan aircraft trajectories taking into account multiple factors including weather, delays, and other random factors. STARGATE is a research consortium including ALTYS, ENAC (Ecole Nationale de l’Aviation Civile) and ONERA (The French Aerospace Lab).

Developing the cockpit of the future

ALTYS has been a member of the IKKY consortium alongside major industry actors including Thales, Airbus, Dassault Aviation. The IKKY project is aimed at optimizing cockpit system architectures through improvements to various software systems. ALTYS provides a number of communications stack elements that are integrated into the Integrated Modular Avionics (IMA) environment used in IKKY. We also provide a realistic test environment that enables full flight virtualization.

Software-Defined Radio

We have dedicated a significant portion of R&D activity to the development of software-defined radio (SDR) solutions for ATM and CNS. This research has led us to develop a portfolio of software-defined radio equipment.
