Brazil’s drone operations are governed by multiple authorities, each with a distinct role. The National Civil Aviation Agency is the primary regulator for unmanned aircraft – it issues regulations, oversees drone registration, pilot licensing, and airworthiness certification anac.gov.br ts2.tech. Working alongside ANAC is the Department of Airspace Control, which manages the airspace and flight permissions for drones. DECEA sets operational rules for where and how drones can fly and runs the online system SARPAS for requesting flight authorizations anac.gov.br ts2.tech. Another key agency is ANATEL, responsible for regulating the radio frequencies and wireless equipment on drones anac.gov.br ts2.tech. ANATEL ensures that drone controllers and video transmitters use approved frequency bands and power levels – drones must have ANATEL certification labels, especially if imported, to prevent harmful interference. In practice, this means if you buy a drone in Brazil it should already be ANATEL-approved, but bringing a foreign drone or custom radio could require special approval. Finally, other bodies like the Ministry of Defense and local law enforcement get involved in security matters. For instance, flying near military bases or national borders may need defense authorization ts2.tech ts2.tech, and police can enforce laws if a drone is used for illicit purposes
