The Amazon Surveillance System or SIVAM (Portuguese: Sistema de Vigilância da Amazônia), is a complex surveillance system used for monitoring the "legal Amazon area". This area includes the Brazilian rainforest, to curb the trafficking of illegal narcotics and to curb illegal logging or burning of the forest. The system utilizes a mixture of fixed and mobile ground radar, as well as airborne surveillance using the Embraer ERJ 145. The combined platform is called the R-99. The U.S. military contractor Raytheon, the Brazilian firm ATECH, the Canadian Aerospace company MacDonald Dettwiler (MDA) and Embraer won the tender to build the SIVAM system. Today, the project has delivered its equipment to the government, creating the SIPAM (Amazonian Protection System) and enhancing the Brazilian Airspace Control System. SIPAM headquarters are located in Brasília, Brazil.
