Longjiang-2 / LO-94 in Lunar Orbit

A cartoon movie has been made that tells the story of the student-built
spacecraft Longjiang-2 / Lunar-OSCAR-94 which went into lunar orbit and
transmitted SSDV images back to radio amateurs on Earth.

Longjiang-2 / LO-94, developed by students and researchers at the Harbin
Institute of Technology, is the worlds smallest spacecraft to enter lunar
orbit independently. It was launched on May 20, 2018 and radio amateurs
tracked its progress as it traveled towards the Moon and successfully
entered lunar orbit.

The spacecraft transmitted signals back to Earth on 435.400 and 436.400
MHz. The amateur radio mode SSDV (Slow Scan Digital Video) was used to send
back pictures of the Moon and WSJT JT4G was used for messages.

Two VHF/UHF SDR transceivers onboard were used to provide the beacon,
telemetry, telecommand, digital image downlink and a GMSK-JT4 repeater,
transmitting power was about 2 watts.
