NEXUS , NE xt generation XU nique S atellite, including Fuji-OSCAR 99 and FO-99 , is a Japanese 1U CubeSat , jointly by the Nihon University and the Japanese AMSAT developed organization, the JAMSAT. The Latin word NEXUS has meanings such as bond and connection and is also intended to stand for the collaboration between Nihon University and JAMSAT. After the successful start and the reception of the first telemetry, the AMSAT-NA assigned the OSCAR number 99 , so that the satellite also bears the designation "Fuji-OSCAR 99".
