Mission Details

JSSW-4

The JSSW (Ji Shu Shiyan Weixing) series of satellites, also known as CK (Chang Kong) or Project 701, was an experimental series of Chinese satellites.

These satellites were likely technological demonstration missions, but the exact purpose has not been disclosed. No signals from the satellites were received in the west, hinting at a military mission that only transmitted while flying over China. An ELINT mission has been speculated, as well as an imaging mission, probably using television or radio transmission of scanned film images. None of the satellites performed manoeuvres in orbit.
