A generation ago, building and launching a satellite was the exclusive domain of governments and large aerospace corporations. A communications satellite might weigh several tons, cost hundreds of millions of dollars, and take a decade from concept to orbit. Today, a university team can build a functioning satellite the size of a shoebox for $50,000, book a ride to orbit on a rideshare mission, and have it operational within two years. The miniaturization revolution has democratized space in ways that are still unfolding.
The CubeSat standard — a modular format based on 10×10×10 centimeter units that can be combined into larger configurations — was developed at California Polytechnic State University and Stanford in 1999 as an educational tool. It has since become the foundation of a global small satellite industry worth billions of dollars annually, serving commercial, scientific, and national security applications.
Constellation Economics
The most transformative application of small satellite technology is the large low Earth orbit (LEO) constellation. SpaceX’s Starlink, with over 6,000 satellites already in orbit and plans for tens of thousands more, has demonstrated that a constellation of small satellites can provide global broadband internet coverage with latency characteristics competitive with fiber optics — something geostationary satellites, positioned 35,786 kilometers above Earth, cannot match.
Amazon’s Project Kuiper, OneWeb (now part of Eutelsat), and China’s SatNet are pursuing similar architectures. The combined effect is a fundamental shift in how global internet infrastructure is conceived: instead of a small number of very expensive, very capable satellites in high orbits, the new model uses thousands of small, relatively inexpensive satellites in low orbits, replacing them frequently as technology improves.
Earth Observation at Scale
Beyond communications, Earth observation has been transformed by small satellites. Companies like Planet Labs operate fleets of hundreds of small imaging satellites that can photograph every point on Earth’s surface every day — a revisit rate that was previously impossible. This daily global imagery has applications ranging from agricultural monitoring and deforestation tracking to military intelligence and financial analysis.
For a country like Brazil, with the world’s largest tropical forest, extensive agricultural production, and challenging border surveillance requirements, this kind of persistent Earth observation capability has obvious strategic and economic value. The Amazon Fund and Brazil’s INPE (National Institute for Space Research) have been early users of commercial small satellite data for deforestation monitoring.
Brazil’s Small Satellite Ecosystem
Brazil is developing its own small satellite industrial base. The Amazônia-1 satellite, launched in 2021, was Brazil’s first independently designed and built Earth observation satellite, produced by INPE. The program demonstrated that Brazilian industry can develop and operate space systems without total dependence on foreign prime contractors.
Private Brazilian space startups, including Orion Sistemas Espaciais and others, are developing small satellite components and services, supported by the AEB’s new commercial space policy framework that seeks to create conditions for a domestic NewSpace industry. The global small satellite boom is an opportunity Brazil is positioned to participate in — if investment and policy support keep pace with the technology.
