The fourth pair of SJ-6 satellites was launched on Oct 6, 2010 into a 588 x 604 km x 97.8 deg orbit. Shijian liuhao 4 zu A xing is a small satellite built by CAST/Beijing. Its companion, Shijian liuhao 4 zu B xing, is a larger satellite (perhaps 1000 kg) built by the Shanghai academy. The satellites may have some kind of military surveillance role.
As noted by to Igor Lissov on nasaspaceflight.com, the B xing spent from Oct 10 to 14 in a lower 566 x 604 km orbit to adjust its orbital position relative to A, and then moved up again to match orbits with A.
