Seems like it could be a confusion with a statement that the YG-30 Groups would work with each other (as opposed to with the original YG-30)

It's hard to evaluate without seeing the original Xinhua release their claim is based on, preferably in its Chinese version.

It's hard to evaluate without seeing the original Xinhua release their claim is based on, preferably in its Chinese version.Was it an extrapolation of the 2nd paragraph of the original Xinhua press release (http://news.xinhuanet.com/politics/2017-09/29/c_1121745112.htm ) which prompted the SCMP author to talk about a "constellation" involving the earlier YG-30?
Following from Jonathan's comment, this is what I posted on September 29 in the thread for the first cluster in this constellation:"Maybe the Chinese screwed up with the numbering system or mis-translated it into western numbers, and it should be Yaogan Weixing 31A, B and C?"
I bet that's it. "Remote sensing satellite No. 30 uses multi-satellitet networking mode, mainly for electromagnetic environment detection and related technical tests. Since the satellite came into operation on August 21, Xichang Satellite Launch Center has conducted a comprehensive review on organization and management, command operation, facilities and equipment, test instruments and so on"I interpret that as referring not to the original YG-30 but the YG-30 Group satellites, and the Aug 21 referring tostart of ground tests at Xichang. So I think the claim that there is an admitted link to the original YG-30 is very weak.And indeed I still suspect that someone goofed and it should have been YG-31 Group 01 etc.
