Aerospace & Defence

Enabling advanced technology in a safe and cost efficient way.


With a wide range of domains encompassing aeronautics, civil, defence and space, this industry faces a number of challenges.

  • The Defence sector is seeing budgets cuts world-wide driving the requirement to reduce costs through the use of COTS, simulation and generally re-use and upgrade of platforms. However, the defence sector is growing where top-end technology brings an edge, for instance in areas such as UAV/UASs (Unmanned Air Vehicles/Systems), advanced sensors, image processing, network technology, simulation, cyber-security and cyber-attack.
  •  In the Aeronautic Civil sector we see the increased use of model-based engineering methods and simulation, as well as the use of COTS and open source technologies. Key technologies are being deployed in areas such as: advanced cockpit design, open and connected infotainment systems for passengers, remote diagnostics and advanced power management for all-electric planes. All this in a context of the emergence of the new DO-178C.
  • In Air Traffic Management (ATM), the key challenge is to increase capacity while maintaining or improving safety, reducing cost and emissions. In Europe, the Single European Sky aims to treble capacity by 2020, a key driver of which is the use of advanced technologies. Technology is increasingly being underpinned by complex software, much of which is safety-related and therefore subject to the demands of safety regulation. Safety regulation is itself undergoing changes with Aviation Safety Agencies taking a central role in defining safety regulation for ATM.
  • In the Space sector cost is also a challenge especially because of the increased competition in a context of rapid growth in demand for space flights with a range of new customer needs (telecom, tourism, military etc.). This drives the industry to use increasingly more COTS and open products, and also look for low cost/low power satellite solutions.


Intelligent Systems / Altran has significant experience in aerospace & defence, both civil & military, with major projects completed in civil & military avionics, unmanned air systems, land systems, naval systems, space and air traffic management.
