AO-6 was AMSAT's first long-life satellite, and was built with participants from Australia and West Germany.

[1] The IPS (Interpreter for Process Structures) programming language was specifically written for the RCA 1802 AMSAT Phase III satellite.

Many of these countries have their own AMSAT affiliate, some of which are noted below: The AMSAT Phase system describes an amateur satellite based upon its capabilities or mode of operation and roughly parallel the development of amateur satellites.

Most amateur satellites do not receive their sequential OSCAR designation until after they are successfully in orbit, and then only at the request of the launching organization.

AMSAT built a series of five 1U CubeSats to carry university experiments, including a camera, and mode U/V FM repeaters.

[20] Fox-1D (AO-92) was launched on 12 January 2018 on the PSLV-C40 mission from Satish Dhawan Space Centre in Sriharikota, India.

Fox-1Cliff was launched from Vandenberg Air Force Base aboard the SpaceX Falcon-9 SSO-A rocket on 3 December 2018.

Although the beacon has not been heard, the linear transponder is at least partially functioning with a low level downlink signal.

The GOLF series is designed to test technologies for future high Earth orbit (HEO) missions.

AMSAT also supports STEM education and has developed a CubeSat Simulator as part of these efforts.

The U.S. Air Force FalconSAT-3 was turned over to AMSAT for amateur radio use in late September 2017.
