Company information

Introduction & Company Presentation Si ATM is located in Sundbyberg, Sweden and was established in 1981 . It was founded by personnel from the Swedish Air Traffic Management (ATM) industry with extensive Air Traffic Control (ATC) experience. This experience was acquired from developing the highly sophisticated ATC systems ATCAS and TERCAS, which were produced in Sweden at the end of the 1970's, and were installed in Sweden and Russia. Activity focus Si ATM has throughout its existence systematically focused on activities in the ATM area.

Initially, the company participated in ATM consultant projects including contributions in sizeable ATC upgrade and modernization projects. Si ATM predominantly worked on projects in the Swedish market for the Swedish Civil Aviation Authorities (CAA), known today as the LFV Group. However since its incorporation Si ATM has gradually expanded its capabilities by providing systems and services for other CAAs and companies in the ATM industry around the world.
