The images suggest that the launch was from the newer pad at TSLC.
The payload fairing is of the type used on the CZ-4C. I haven't seen it used on a 4B before - this could support my theory that this was a 4C not a 4B. We'll have a better idea when the orbits are published.

Want to bet?
Yaogan Weixing 5 480 x 492 km x 97.4
CZ stage 360 x 486 km x 97.3
So, I tend to agree CZ-4C but the lower orbit compared to other YW satellites
does complicate things...

The initial orbital data and the launch time for Yaogan 5 look very similar to those seen for the three Jianbing-3/Ziyuan-2 satellites.
Could Yaogan 5 be the first in a Jianbing-3B (or even Jianbing-7??!!) follow-on satellite series?

Many months ago a source in China told me that the first Jian Bing-7 was going to be the YaoGan-5.

It looks as if the third of the Jianbing-3/Ziyuan-2 satellites was moved well away from the Jianbing-3 operating altitude, with an apparently final orbit being reached about a month ago. Clearing the skies for the second generation satellite, perhaps?
And if both Jianbing-6 and Jianbing-7 are photo imaging satellites, I wonder how they compare. Different platforms, presumably: maybe the higher JB6 orbit is for area survey work and the lower JB7 orbit is for close look work?
BTW, has anyone seen a photograph or description of the CAST-2000 platform which apprently JB-6/Yaogans 2 and 4 use?

Very good observation!
It's a matter of agreement what to name Jianbing 7. Two years ago, JB-5 and JB-7 could be occasionally found on the net while mentions of JB-6 existed only in fantastic novels :-)
Now the extremist sort of observers tend to believe the following:
Yaogan weixing 1 = JB-5
Yaogan weixing 2 = JB-6
Yaogan weixing 3 = JB-7
Yaogan weixing 4 = JB-8
Yaogan weixing 5 = JB-9 :-)
My understanding is that we don't need such a set of designations. My feeling is that YW-1 and YW-3 are JB-5s, YW-2 and YW-4 are JB-6s, and YW-5 looks a good candidate for JB-7.

I think maybe you mean YW not SW??

Plus the obvious connection. The Jianbing-3 satellites used the CZ-4B for Taiyuan, as did Yaogan 5.

An answer not exactly to your question but here
http://v.cctv.com/html/xinwenlianbo/2008/12/xinwenlianbo_300_20081215_14.shtml you can see the launch and the 3D graphics of orbit insertion and the satellite with two solar panels in deployment. Can't judge if the graphics represent the real bird.

Xinhua says CZ-4B. Did Xinhua say CZ-4C for the previous Yaogan launches from Taiyuan, or did it specify CZ-4B for those?
As for the new launch pad, I would suggest this spot as one candidate for its location, shown under construction on Google about 2 km north-northwest of the original CZ-4 pad.

Thank you, Igor! Don't those two imaging systems on the satellite remind you of the pair carried on the front of the Shenzhou 5 orbital module? Could be a coincidence, of course.

I still don't think YG series have much military applications. I think the images got from those satellites were still low resolution and have little military value. One Chinese scientist said that China's remote sensing technology was still behind India last year. And according to the white paper published by CNSA in 2006, China was going to develop high resolution earth observation satellites in this five years plan. This is only the second year of this five years plan, I don't think those satellites can be developped that quickly.
