Why us

Why you should work with Si ATM

The Si ATM products and expertise has grown continuously since we started in 1981. Based in Sundbyberg, in the Greater Stockholm region of Sweden, we have for more than 40 years systematically focused on activities across the ATM area. During this time, we have continuously enhanced our systems. Consequently, we are perfectly positioned to deliver advanced, cutting edge ATC/ATM systems to CAAs, ANSPs and Airport Operators throughout the world.


“Throughout the world, Civil Aviation Administrations (CAAs) and Air Navigation Service Providers (ANSPs) continually struggle to cope with the pressures of increasing air traffic. This is not helped by the fact that budgets are often limited and few can afford to invest in a totally new Air Traffic Control (ATC) system. Furthermore, CAAs and ANSPs are cautious about adopting totally new systems due to the safety critical nature of the operations.”


In recognition of this issue, we at Si ATM have developed a modular, platform independent and cost effective ATC concept that is able to meet the requirements of CAAs and ANSPs. Our ATC systems have been in operational use for a considerable period of time at airports and area control centres in Sweden, Russia, Latvia and Bahrain. New cutting edge ATM systems are now being installed in for instance Moldavia.

The Si ATM ATC concept will provide you with…

Step-by-step upgrading of systems to a state-of-the-art level with minimal interference to the ongoing daily operations.


A quick development phase by reusing software.


‘Future-proof’ investments due to platform independence, but with emphasis on Linux.


Cost efficiency through the reuse of systems, quick development phase and platform independence.


Phased implementation methods that will help prevent delays, rising costs, temporary solutions and dead ends.


Our commitment to involve your specialists and working controllers in all phases of the project.

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.

Rapid prototyping where we involve you

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 Si ATM, 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

Si ATM 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.
