OSCAR satellites

OSCAR satellites, short for "Orbiting Satellite Carrying Amateur Radio," are small, amateur radio spacecraft launched by hobbyists and organizations. They serve as communication tools for licensed radio operators worldwide, enabling voice, data, or telemetry transmissions between ground stations. These satellites also promote education and public interest in space and radio science. Typically, OSCARs are simple, affordable, and designed for long-term operation in orbit, fostering international collaboration and experimentation among amateur radio enthusiasts and students.
