About
VCUB1 is Visiona’s nanosatellite platform and the first Earth-observation and data-collection satellite conceived and designed end-to-end by Brazilian industry. Built to ECSS and NASA standards using Model-Based Systems Engineering, the scalable 3U-to-27U+ architecture carries a dual payload capable of simultaneously collecting optical imagery and communications/IoT data. The mission validated Brazil’s first domestically developed satellite Attitude and Orbit Control System (AOCS), an onboard software-defined radio (SDR), and an ultra-stabilized platform with reaction wheels for high radiometric and geometric image quality. VCUB1 follows a software-defined-satellite concept, allowing in-flight reconfiguration for new applications, and its bidirectional UHF data-collection payload targets hydro-meteorological sensor networks as well as future IoT and communications missions. The camera payload (OPTO 3UCAM) uses a push-broom sensor with Time-Delayed Integration (TDI) and a high-frequency gyroscope for motion compensation, delivering 3.5 m panchromatic resolution optimized for agricultural and environmental monitoring, including Red Edge band imaging. The program was developed with a network of Brazilian technology partners including OPTO, AMS Kepler, Metalcard and Orbital Engenharia, with financial support from EMBRAPII and the SENAI Innovation Institute.
