AMSAT

AMSAT, short for Radio Amateur Satellite Corporation, is a global organization of amateur radio operators ("hams") that designs, builds, launches, and operates satellites carrying amateur radio payloads. These satellites, often referred to as OSCARs, facilitate communication between amateur radio stations using amateur radio frequencies. AMSAT partners with government, industry, and educational institutions, including NASA and ESA, to foster amateur radio's participation in space research and STEM education.
