Spaceflightfans.cn giving a interesting schedule remark about the next YG-30 group launch.
They are giving the January 21 launch date for YG-30-3 sats.

Cross-post from the Chinese launch schedule thread:
Spaceflightfans.cn is giving the launch date for YG-30-03 as December 27 and January 9 for GJ-3/4.
Well, it says "tbd" (待定) in both cases
So, possibly wild guesses...

Launch code is 07-83.
One explanation why launch code is 07-83 and not 07-82 could be that Beidou-3 MEO3/MEO4 was initially supposed to launch before this one (to be confirmed after next Beidou launch)

I continue to be confused by this constellation - if it is SIGINT, why is it only at 35 degree inc?
Makes it unlikely that it is a global system aimed at e.g. US and Russia
- Operating in conjunction with a polar constellation?
- Targeted specifically at India?
- Targeted at South China Sea naval activities?
- Actually a comms constellation to support users in China only?

A Long March-2C rocket launched the third group of three Yaogan-30 remote sensing satellites from Xichang Satellite Launch Center, Sichuan province, on 25 December 2017, at 19:44 UTC (03:44 local time). According to official sources, the satellites entered their preset orbit.

it is quite possible that they work together but all we know from the State media and the forums in China is that YG-30 operates with the YG-30 Groups and that we may see additional launches for this Constellation in 2018 to further expand coverage in this multi inclination constellation.

I'm guessing this numbering is the manufacturer's and applies to the CX-5 name (Chuangxin-5 07 xing, etc)
rather than to the YG-30 name which always seems to be used with the 'zu' (group) numbering, YG 30 hao 03 zu 01 zing etc.

I doubt it very much because orbital heights are different and hence there is no synchronization in movements of YG-24/GF-9/YG-30 optical birds with the three triplets which are not optical per official statements.
Yet I'm open to a possibility of three additional launches to bring the constellation to six planes x three satellites.

The "original" is a Hong Kong newspaper's English language restatement citing a Xinhua statement. 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?

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 to
start 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.

Following from Jonathan's comment, this is what I posted on September 29 in the thread for the first cluster in this constellation:

As I'm sure you know, we are now sure it's not a mistranslation - it's definitely 30 and not 31 in the Chinese: 三十
But it could be a mistake that they were too embarrassed to correct! Or, they are deliberately trolling us.

The sentence 自卫星８月２１日进场以来 can be translated as "Since the arrival of the satellite on August 21,..' which fits all the more with your interpretation.
