  SJ-6 Chinese military surveillance satellite constellation. Each launch was said to consist of a primary satellite using the CAST968 bus and a subsatellite built by SAST Shanghai. Five pairs were launched from ?Taiyuan by the CZ-4B launch vehicle into 590 km, 97.7 deg inclination sun synchronous orbits from 2009. Reported to carry systems for optically tracking satellites in orbit. In 2013 SJ-15 was launched from Jiuquan, and SJ-16 from Taiyuan, in very similar but slightly different orbits. These may have been the successor system.
