NSSDCA/COSPAR ID: 1979-009A
The Experimental Communication Satellite (ECS) was another in a series of Japanese satellites designed to develop national communications capabilities. It was a follow-up to the ETS 2 (1977-014A) test satellite. It consisted of a spin-stabilized cylinder with the curved surfaces covered by solar cells. The diameter of the cylinder was 1.4 m. From one end of the cylinder four short, VHF, monopole antennas were extended. On the other end was mounted a despun, two-disk array of antennas -- one for C-band, and the other for K-band communication. The satellite height including antennas was 1.8 m. The satellite was designed for a lifetime on location near 145 deg e. The satellite utilized frequencies of 10, 40, and 120 MHz plus 4, 6, 32, and 35 gHz in addition to the 137/148 MHz telemetry/command frequencies. Propagation studies and communications experiments, including experiments with satellite CS, were its objectives.
