title: FROM SPACE TO EARTH: HOW CUBESAT SATELLITES TRANSMIT THEIR DATA
abstract: CubeSat satellites have become an accessible platform for scientific and educational missions in low Earth orbit. This paper presents an overview of how CubeSat systems collect, transmit, and deliver data from space to ground operators. The process includes onboard data acquisition, radio communication through dedicated frequency bands, and subsequent decoding and visualization on Earth. The study highlights the role of affordable technologies, open-source tools, and international collaboration
