ITF-2 is a Japanese amateur radio satellite . It was built at Tsukuba State University . The abbreviation "ITF" stands for the university slogan: "Imagine The Future". ITF-2 is the successor to ITF-1, which started in 2014 but has never received any signals. The frequencies were coordinated by the IARU . On June 11, 2017, AMSAT North America awarded the OSCAR designation Tsukuba-OSCAR-89 (TO-89). ITF-2 is used to test microcontrollers under space conditions. The satellite has a miniature antenna (Ultra Small Antenna) in the form of a folded conductor track (1/20 lambda) on a circuit board that is mounted on the outside of the satellite. Receipt of telemetry is confirmed by Tsukuba University with a QSL card .
