Abstract
Japan Amateur Radio League, Inc, (JARL) supported by JARL′s Satellite Repeater Group (JAMSAT) is developing the first Japanese amateur radio satellite (JAS-1). JAS-1 is 26 faced polyhedron shape, about 40 cm by 40 m by 47 cm (16″ x 16″ x 19″) in size and 50 kg (110 Ibs.) in weight. JAS-1, which uses 145 MHz band for uplink and 435 MHz band for downlink, has two transponders each for analog and digital communications for world-wide amateur radio. These onboard transponders were manufactured by JAMSAT. JAS-1 will be launched in February 1986 by H-I test rocket of National Space Development Agency of Japan (NASDA).
