Shijian 2A



The announced missions of the three SJ-2 (Shi Jian - Practice) spacecraft launched on a single booster included ionospheric and atmospheric studies. This cover story was frequently used by early American electronic intelligence satellites launched by the US Navy, and the mass and orbital parameters (200 by 1600 km orbits at 59.4 deg inclination) of the SJ-2 spacecraft were consistent both with the announced missions as well as with electronic intelligence (ELINT) applications.
