A CZ-11 will be launched from Jiuquan at the end of March or beginning of April carrying the second group of Zhuhai-1 sats together with other small payloads.
-
When were the first set of Zhuai-1 satellites launched? I couldn't find Zhuai-1 in Gunter's space page.
-
This should be Zhuhai-1

Thanks Little Flying Horse. The spelling was incorrect, which is why I couldn't find the satellite. Satori has now corrected the spelling. :-)

According to Spaceflightfans.cn, the launch will take place in early April.

Should that be Zhuhai-1C and Zhuhai-1D?
-
Expected launch codename: 01-91
-
According some information from the 9ifly Chinese space forum, the satellites in board will be a OVS-2 upgraded version of Zhuhai-1 video sat and 4 hyperspectral sats from the OHS-2 series.

Maybe the designation OHS-2 is a typo. This source
http://www.zhsw.gov.cn/sww_xcb/xcgz/xcwh/201803/t20180307_25922458.html
is calling the hyperspectral sats OHS-1A/B/C/D.
-
Can any of our Chinese speakers help with this? Did I understand correctly that the new OVS-2 satellite is named 'Guiyang-1'?

And also with this? The Qingkeda-1 satellite will also be on board as one of the hyperspectral satellites?

Yup. Qingkeda-1 is OHS-1-01 and Guiyang-1 is OHS-1-03.
As I understand the payload is 4 x OHS-1 & 1 x OVS-2.
-

Thanks. So which payload is Zhuhai-1?

The whole imaging satellites constellation is called Zhuhai-1. ;)
-
Yup. Qingkeda-1 is OHS-1-01 and Guiyang-1 is OHS-1-03.
Qingkeda is the short for 青岛科技大学（Qingdao University of Science and Technology), and Guiyang is the provincial center of Guizhou. So these are names after sponsors/participants.

And possibly, the other sats will also have their own names.

From the current schedule the following is listed

Apparently this is how the 5 satellites are stacked for today's launch

Launch time should be around these few minutes. News still pending right now....

The sign says OHS-2 instead of OHS-1. Which one is correct?!
-
Looks like the launch did happen and was successful; pending confirmation.
-
Launch time seems to be 04:42 UTC. (source (http://weibo.com/1960601312/GdRLQxyxz?refer_flag=1001030103_))
Confirmation from state media still pending.

Finally CALT has confirmed that the launch was successful: https://mp.weixin.qq.com/s/DgF9SghYUt-Aw4GCIVUp1g (https://mp.weixin.qq.com/s/DgF9SghYUt-Aw4GCIVUp1g)
This launch used CZ-11 s/n Y4.

Two of the launch photos in high-res (credit: Wang Jiangbo/Xinhua) - it's pretty hard to get one before for the CZ-11!
Also the company's logo looks rather......classical. ;)

Someone also wondered about that on the Chinese forum I visit - perhaps the company simply skipped the 1st generation for the hyper-spectral sats. :-\

JIUQUAN, April 26 (Xinhua) -- China on Thursday sent five Zhuhai-1 remote sensing satellites into space on a single carrier rocket.
The Long March-11 carrier rocket lifted off from Jiuquan Satellite Launch Center in northwest China at 12:42 p.m. The launch was the 272nd flight mission for the Long March series of carrier rockets.
Zhuhai-1 is a commercial remote sensing satellite constellation invested in by Zhuhai Orbita Aerospace Science and Technology Co. It will provide data services for areas including agriculture, land and water resources, environmental protection and transport.
China launched two Zhuhai-1 satellites on June 15, 2017

Refers to the satellites as Zhuhai-1 Group 02 ("zhuhai yi hao 02 zu")
and as OVS-2 and OHS-01/02/03/04
OVS-2 mass given as 90 kg, no data on OHS masses.

Two satellites of the five have maneuvered to a 513 km height orbit.

The third one did the same.
