Posted by John McHale CERRO MACO, Columbia, 7 Sept. 2010. SELEX Sistemi Integrati, a Finmeccanica company, won a contract from the Aeronautica Civil de Colombia, for the upgrade of an air traffic control (ATC)radar system set in Cerro Maco, Columbia, near San Jacinto in the region of Bolivar. The contract covers a hardware and software upgrade to the ATCR 22M primary radar and the SIR-M secondary radar. The solid state technology which will be implemented into the primary radar, will make it possible to avoid the spare parts obsolescence, while the secondary radar upgrade will enable the greater management information and data exchange with the airplanes, enhancing the performance of air traffic surveillance and the flight security, SELEX officials say. The upgrade will take nine months and includes the relevant logistic support. SELEX Sistemi Integrati has been in Colombia for about 30 years and has provided about the 80 percent of the air traffic management systems placed into the Colombian airports.
