A US congressional report released February 26 alleges that a satellite ground station in Bahia, northeast Brazil, functions as an unofficial Chinese military installation capable of real-time surveillance of space objects and foreign military assets across South America. The claim, buried in a document titled “Drawing Latin America into China’s Orbit,” has ricocheted through Brazilian media.
The facility in question is the Tucano Ground Station, a product of a 2020 partnership between Ayla Space, a Brazilian aerospace startup, and Beijing Tianlian Space Technology, a Chinese satellite firm. The stated purpose is analysing Earth-observation satellite data within Brazilian territory.
What the Report Claims
The congressional committee classifies the Tucano station as “unofficial” and asserts it provides China with the ability to identify foreign military assets and track space objects in real time. The report states the facility gives Beijing a channel to observe and influence Brazilian military space doctrine while establishing a permanent foothold in a region it describes as vital to US national security.
A second Brazilian installation is also flagged: a joint China-Brazil radio astronomy laboratory in the Serra do Urubu mountains of Paraíba state, run with two Brazilian federal universities. The committee warns that the Chinese partner institute is embedded in Beijing’s defence industrial base, making the laboratory’s deep-space observation systems potentially applicable for military intelligence.
A Hemisphere-Wide Pattern
Brazil is not the only country named. The report identifies at least 11 Chinese-linked space facilities across Argentina, Venezuela, Bolivia, Chile, and Brazil that the committee says may have dual-use military applications. The best-known is the Espacio Lejano deep-space station in Argentina’s Neuquén province, a 35-metre antenna operating under a 50-year lease with limited Argentine oversight, which has drawn sustained US criticism.
The committee argues that China’s military-civil fusion doctrine makes it impossible to separate commercial space cooperation from potential military use. It recommends halting the expansion of Chinese space infrastructure in the hemisphere and updating the Wolf Amendment, which restricts NASA cooperation with China, to close what it calls growing loopholes.
The Response — and the Silence
Brazil’s Foreign Ministry has not officially responded to the report’s claims. China’s foreign ministry spokesperson said cooperation with Latin America is civilian in nature and aimed at improving disaster prevention, agricultural monitoring, and climate response, adding that drawing geopolitical battle lines in the region would benefit no one.
What It Means
The report lands at a sensitive moment. Brazil is China’s largest trading partner in Latin America and is navigating tense relations with Washington amid the Iran crisis and tariff disputes. The committee names Brazil 15 times — a frequency that signals growing US scrutiny of Brasília’s technology ties with Beijing, particularly in sectors where civilian and defence applications blur.
Whether the Tucano Ground Station is a satellite data facility or something more is a question the report raises but does not conclusively answer. What it makes clear is that, from Washington’s perspective, the ambiguity itself is the threat.
