Launch activities at the Xichang Satellite Launch Center for 2018 ended with the launch of another secretive Tongxin Jishu Shiyan Weixing (TJSW) satellite on Christmas Day. The launch took place at 17:00 UTC using a Long March-3C/G2 (Chang Zheng-3C/G2) launch vehicle from the LC3 launch complex.
As with the previous launch of Communications Engineering Test Satellites, not much information is available regarding the satellite.
When TJSW-1 was launched on September 12, 2015, Chinese authorities said the new satellite was a geostationary communications technology test satellite to be mainly used to conduct a test on Ka-band in broadband communication (frequencies between 27 and 40 GHz).
Previous to the launch of TJSW-1, there were rumors circling on specialized Chinese space forums that pointed to the launch of the first Great Wall (Changcheng) satellite, a new series of Chinese satellites dedicated to early warning similar to the American Space Based Infra-Red Sensor satellites.
Back then, Japan’s Kyodo News reported that China was building a missile defense system to detect a ballistic missile attack. The report was based on Chinese military documents that referred to the development of an experimental early warning satellite program.
