Why us

Why you should work with Si ATM

Located in Stockholm, Sweden, we have dedicated over four decades to advancing air traffic management (ATM) solutions. Our commitment has enabled us to significantly enhance our systems, positioning us as a leading provider of advanced air traffic control (ATC)/ATM systems to Civil Aviation Administrations (CAAs), Air Navigation Service Providers (ANSPs), and Airport Operators globally.


Civil Aviation Administrations and Air Navigation Service Providers worldwide face the challenge of managing increasing air traffic volumes amid constrained budgets. The investment in entirely new Air Traffic Control systems is often prohibitive, and there is a natural caution towards adopting new systems due to the critical nature of air traffic operations.



Recognizing these challenges, Si ATM has developed a modular, platform-independent, and cost-effective ATC concept designed to meet the diverse needs of CAAs and ANSPs. 

The Si ATM ATC Concept Offers:

  • Step-by-Step System Upgrades: Achieve state-of-the-art capabilities with minimal disruption to daily operations.
  • Rapid Development: Benefit from our approach to reusing software for quicker system development.
  • Future-Proof Investments: Embrace platform independence, with a focus on Linux, to safeguard your technology investments.
  • Cost Efficiency: Our reuse of systems, rapid development, and platform independence ensure cost-effective solutions.
  • Phased Implementation: Avoid delays, rising costs, and temporary solutions with our structured implementation approach.
  • Collaborative Development: Engage your specialists and working controllers in every project phase for tailored solutions.

ATC/ATM building blocks:

The Si ATM system concept is essentially a set of reusable system building blocks facilitating step-by-step substitution of obsolete technology. This means that systems can be upgraded to achieve state-of-the-art performance levels without the need for dramatic changes at any stage.

Our ready-made software modules for radar presentation, flight data processing and other necessary ATM functions can be combined with your specific applications, as required.

Inclusive Rapid prototyping:

Our strategy of reusing software means that we can deliver a quick development phase that is undertaken with the needs of the working controller at the forefront of our minds. We use rapid prototyping methods to create a human-machine interface that closely corresponds to the final version. And our success comes through our commitment to involve your specialists and working controllers in all phases of the project.

Rely on our considerable knowledge of ATC operations:

At SiATM, we fully understand the entire chain of information processing from the smallest component to the controller’s decision. This enables us to implement our system on a step-by-step basis and consequently ongoing operations will not be adversely affected.

Over the years, we have gained a deep understanding of how work is performed in towers, terminal centres and area control centres. The reality is that when developing modern automated systems, knowledge of conventions and traditions of Air Traffic Control is vital; our staff have vast experience of controllers working situations.

Quality Assurance:

SiATM fully recognises the significance of an organised Quality Assurance (QA) activity to enable the successful design, production and operation of complicated automated electronic systems. Therefore, we are certified according to ISO 9001:2015 and have a quality system in operation that is well adapted to the development, production and operation of such complex computerised systems as ATM systems.
