CCTV just reported launch crews in JSLC were preparing for the next launch of CZ-2D. Could it be Jilin-2?

Looks like the launch could take place in the next days (?)

This CZ-2D arrived at JSLC on Oct. 16, so the launch date is definitely in November

There are two CZ-2Ds being preparing for launch in JSLC
These rockets arrived at JSLC on Oct. 16

They do this each time rockets arrive at the railway station?

Maybe for this launch?

One of the CZ-2D at Jiuquan might be for the GJ-1 pair,
but with a launch date of late December I am sure that another one will fly before it (and remember the last two flew from Taiyuan!), so no.

Examining the launch history, the only Yaogan/Jianbing payloads launched on a CZ-2D from Jiuquan are the JB-6 optical reconnaissance/remote sensing satellites: YG-2, 4, 7, 11, 24, and 30.

Gunter's Space Page http://space.skyrocket.de/doc_sdat/yaogan-2.htm lists these as manufactured by CAST.

Launch will take place around 0842UTC according to 9ifly Chinese space forum.

Here's a chain of deduction...

Given the above information, and if YG-31 is the newest spacecraft in the JB-6 program:
Then this launch into SSO would launch at the same time UTC, to the minute, as YG-7, the 3rd member of the JB-6 program.  (Also, a near match in launch dates--YG-7, December 9; YG-31, December 2)

And, therefore, would not YG-31 enter a similar SSO orbit with the same initial LTDN as YG-7?

Is YG-31 meant to replace YG-7, or augment its capabilities?

I do not believe YG-24 and YG-30 (and GF-9 too) are members of the JB-6 series.

From what series do you think they are, Liss?

It is hard to see, if there is a difference between the JB-6 and a JB-6 follow-on series: Same launch vehicle, same fairing, same launch site and same orbit.

I know. There were multiple arguments for the new type:
(1) Four years interval before YG-24 against three years life expectancy of JB-6;
(2) A Chinese report on cameras test on YG-24 which is logical for a new design;
(3) Chief designer/administrator name for YG-24/GF-9/YG-30 was published but not for any of JB-6;
(4) Ground resolution of 2 meters for JB-6 and sub-meter for YG-24.

Not sure if this is related to this launch, if so this won't fly until December 3:

A3661/17 - A TEMPORARY RESTRICTED AREA ESTABLISHED BOUNDED BY:N330743E0981215-N331228E0974709-N340515E0980115-N340028E0982635 BACK TO START. VERTICAL LIMITS:GND-UNL. GND - UNL, 03 DEC 04:04 2017 UNTIL 03 DEC 04:32 2017. CREATED: 01 DEC 06:33 2017

Note that there is another notice (A3662/17) with the exact same words except for listing the effective date as 23 December! I guess this one is a fluke?  ;)

These two NOTAMed areas (in purple below) appear to be close to those for Shiyan-5 launch with CZ-2D on Nov 25, 2013 (in red below)
