SJ 6-01, ..., 6-05

SJ 6-01A / SJ 6-01B

The SJ 6 (Shi Jian 6) series consisted of pairs of technology satellites, which were reported to be used to probe the space environment, radiation and its effects, record space physical environment parameters, and conduct other related space experiments.

The two satellites were built by the Shanghai Academy of Space Flight Technology and Dongfanghong Satellite Company under subcontract to the China Aerospace Science and Technology Corporation. Reportedly the CAST968 platform was used. The scientific instruments aboard the satellites were mainly manufactured by the China Electronics Technology Corporation. A design life of at least two years was announced.

Possibly the mission of the satellites included electronic intelligence (ELINT) technology tests.

The fifth group might be an upgraded design.
