TJS 2 (Tongxin Jishu Shiyan) is a Chinese geostationary communications technology test satellite.
Reportedly the satellite will be mainly used to conduct a test on high speed/multi-frequency wide-band data transfer communication.

China′s first launch of the year was Tongxin Jishu Shiyan Weixing 2 (Communications Technology Experiment Satellite 2). TJSW 2 was developed by the Shanghai team - in contrast to 2015's TJSW 1 which was reported to be from CAST/Beijing. The lack of public information about the TJSW satellites has led to the suspicion that they may really be for defense purposes, possibly for non-communications purposes such as signals intelligence or missile early warning. Nevertheless for the time being I am keeping them on the books as probable military communications satellites.
TJSW 2 appears to have made the burn to circularize its orbit on Jan 6 at 0730 UTC over 114E, but there′s been no TLE data for it since then.
