Presents a historical timeline of amateur radio satellites, beginning with the inaugural _OSCAR 1_ in 1961 and extending through ARISSat-1 in 2011. It outlines the evolution of these orbiting transponders, initially simple battery-operated beacons, into sophisticated platforms supporting educational initiatives, emergency communications, and technology demonstrations. The document highlights the significant contributions of various AMSAT organizations and other entities in developing and deploying these spacecraft. Each entry provides specific launch details, including the date, launch vehicle, and initial orbital parameters such as apogee, perigee, and inclination. For instance, AMSAT-OSCAR 7 (AO-7) launched in 1974 into a 1459.00 x 1440.00 Km orbit, while AMSAT-OSCAR 40 (AO-40) achieved a highly elliptical 58665.00 x 1157.00 Km orbit. The resource also notes the allocated amateur satellite service frequencies, including 29 MHz (10m), 145 MHz (2m), 435 MHz (70cm), 1270 MHz (24cm), and 2400 MHz (13cm). The compilation serves as a concise reference for understanding the progression of amateur satellite technology and operations over five decades, showcasing the collaborative efforts of the global amateur radio community in space communication endeavors. It details the physical characteristics and project affiliations for many of the **20** satellites listed, providing a foundational historical context.
