Atech has a long-standing partnership with Brazil's Department of Airspace Control (DECEA), for which it is implementing Sagitario, an essential system for air traffic management throughout Brazil, and modernising Sigma, a complete solution for air traffic flow management. Both were developed by Atech in partnership with the Brazilian Airspace Control System Implementation Commission (CISCEA). In September 2025 Atech signed a contract with Air Traffic and Navigation Services (ATNS) in South Africa to replace its air traffic flow management system, including airport slot management and UTM flow management.
