China has announced plans to launch 300 (!) Hongyan "global communications" satellites into low orbit, starting later this year.

http://www.xinhuanet.com/english/2018-02/23/c_136994815.htm

Maybe China could launch the lot on a single CZ-5 mission?  ;D   Whatever, I see problems in accurately cataloguing all of these satellites.

[GB Times] Early launch plans for China's Hongyan LEO communications satellite constellation revealed

Quote
The 320-plus-satellite Hongyan constellation will be "made up of 54 core and backbone satellites and 270 other smaller satellites for coordination," Zhang Hongtai, president of the China Academy of Space Technology (CAST) told press last week, adding, "We will launch the first satellite in 2018".
...
The Hongyan constellation will be built in three stages, with the first satellite to be launched this year. Orbiting at an altitude of 1,100 km it will test capabilities and compatibility in low Earth orbit, as well as data transmission capacity.

Zhang said six satellites will be launched before the end of 2020 for network testing. The 54 larger first phase satellites are to be placed in orbit by the year 2023, with 270 smaller satellites placed into orbits to supplement them. Earlier announcements had stated 2021 for completion of the constellation.

Hongyan low-orbit Internet satellite constellation

The first Hongyan satellite is scheduled to be launched by the end of the year.

Low-earth orbit satellite project launched in Chongqing
Quote
CHONGQING, Dec. 1 (Xinhua) -- China's first global mobile satellite communication and internet space project via low earth orbit (LEO) satellites has been launched in southwest China's Chongqing Municipality.
The project has drawn an investment of about 20 billion yuan (about 2.9 billion U.S. dollars) for its first phase, making it the largest investment for a single commercial aerospace program in China, according to the China Aerospace Science and Technology Corporation, which co-founded a company in charge of the project.
The project features hundreds of LEO satellites and a global data processing center, which can help realize global two-way communication in real time under complicated geological conditions 24 hours a day upon completion.
The project is expected to boost development of other sectors, including chips, terminals, system integration, operations and training of talent, said a source of China Aerospace Science and Technology Corporation.

Cross-post:
To clarify, this is the current situation at the original 3 Chinese launch sites:
<snip>
- The one launch [at Jiuquan] that is fairly certain is the CZ-2D (late December), reported to be carrying the first test satellite of CAST's Hongyan LEO comsat constellation. Several unspecified other satellites built by DFH Shenzhen (some say 9 total on this launch) are probably also on board. This launch may be the first time the YZ-3 upper stage is used.

Seems to be it, although I'm slightly surprised (though not contradictory to known data) that this one isn't heading for polar/sun synchronous orbit.

Article dated December 27:
https://gbtimes.com/china-to-launch-first-satellite-for-hongyan-global-internet-satellite-constellation-on-saturday
China to launch first satellite for Hongyan global internet satellite constellation on Saturday
From the article:
Quote
This first Hongyan satellite will be used to test L- and Ka-band communication capabilities and compatibility in low Earth orbit (LEO), as one of nine satellites orbited by 2020 as a pilot demonstration for the Hongyan system, which translates as 'wild goose'.

Also same article:
Quote
According to the Chinese language web portal Satellite World, the launch will also feature the first use of the Yuanzheng-3 (YZ-3) upper stage, designed for for the Long March 2D and Long March 4B launch vehicles.

Which complements the news of this launch carrying secondary payloads:
To clarify, this is the current situation at the original 3 Chinese launch sites:

Jiuquan

- The one launch that is fairly certain is the CZ-2D (late December), reported to be carrying the first test satellite of CAST's Hongyan LEO comsat constellation. Several unspecified other satellites built by DFH Shenzhen (some say 9 total on this launch) are probably also on board.
***

A November 13 article, same publication, same topic: China to launch first Hongyan LEO communications constellation satellite soon
Quote
The satellite will be sent into a 1,100 km altitude orbit by a Long March 2D launch vehicle...

And:
Seems to be it, although I'm slightly surprised (though not contradictory to known data) that this one isn't heading for polar/sun synchronous orbit.

From the NOTAMs locations, can a launch azimuth be deduced?  And therefore, and orbital inclination?

Approximate destination orbit = 1100 km circular? X ?? deg. inclination
***

As the first of 9 test satellites, could Hongyan-1 meet testing needs from a mid-inclination LEO?  Especially if testing is done from and for PRC territory/latitudes?

And some or all of the other 8 test satellites would later go to LPEO/SSO?

According to the subforum list: Yes.  38 orbital launch successes in 39 launches.

There's still an outside chance that the Ziyuan-1-02D launch on a CZ-4B from Taiyuan could happen before the year is out. https://forum.nasaspaceflight.com/index.php?topic=44952.msg1893255#msg1893255

Otherwise, this launch is the last orbital launch for Earth this year!

Photo of the satellite. Article is saying this is the last launch of the year. I count 39 launches from China with one failure. The 37 would be excluding ZQ-1 and KZ-1A.

"The launch was the No. 297 flight of the Long March series of launch vehicles and the last aerospace launch of space science and technology in 2018, with all 37 aerospace launch missions being successful throughout the year, with the number of launches ranking first in the world."

If Yunhai-2 is a weather constellation as suggested, do we have any idea if it is  traditional imaging,
or perhaps GNSS-RO (like the Spire Lemurs)?   Has China talked about GNSS-RO meteorology at all? Seems like an obvious think for them to try out using Beidou and LEO sats.

Looking at the stories linked above, it seems that the Hongyan test satellite has been named 'Chongqing'
重庆号
It is built by Shenzhen Hangtian DFH HIT Weixing YG, with comms payload by CAST's Xi'an branch,
and is owned by Hangtian Keji Jituan DFH Weixing Yidong Tongxin YG 航天科技集团东方红卫星移动通信有限公司
(CASC DFH Mobile Communications Co)

It also seems that YZ-3 is built by SAST, not CALT.  I had thought that YZ-1 and perhaps 2 were CALT stages, is that right?

Yunhai-2 are also built by Shenzen Hangtian DFH HIT.

and then deorbited itself at the end?

or perhaps GNSS-RO (like the Spire Lemurs)?   Has China talked about GNSS-RO meteorology at all? Seems like an obvious think for them to try out using Beidou and LEO sats.

GPS-RO it is indeed: http://www.9ifly.cn/forum.php?mod=redirect&goto=findpost&ptid=10832&pid=633888

No, it is the cluster of the 6 Yunhai-2 satellites attached to YZ-3. Maybe Hongyan-1 was positioned at the top of the stage and was released first. I have enlarged a best available picture of Yunhai-2 taken from the JSLC screen.

Thanks! The image is just after second stage separation, so Hongyan 1 should still be attached. Maybe Hongyan 1 is in the middle of the six Yunhai-2 satellites.
