SJ4, launched on the first Chang Zheng 3A test flight, carried a scientific payload from the Chinese Academy of Sciences. The 396 kg satellite studied the radiation belts at synchronous altitudes, probably to support future comsat design. SJ4 was a 1.6m dia 2.2m long octahedral cylinder with a small boom.
