Thanks Steve for the coverage. That sure was frustrating finding out what you viewing wasn't live at all.

https://news.sina.com.cn/c/2018-12-07/doc-ihmutuec7037961.shtml  says   7 IoT tech verification sats
from Beijing Jiutian Satellite Tech Development Co Ltd (CommSat) and 3 remote sensing new technology test sats
(yaogan xin jishu shiyan weixing) from Tianyi

If this is correct, no MinoSpace Weina or Guoxing Aerospace payloads.

A short description of the other satellites.

http://www.9ifly.cn/forum.php?mod=viewthread&tid=68540&page=13&authorid=10636

"The 2 Saudi main stars, together with the 7 IoT technology verification satellites on board and 3 test satellites for new remote sensing technologies, amounted to a total of 12 satellites, all entering the intended orbit."

Hua Mi Xing (华米星), According to Huami Technology Yhis is the first trial of wearable devices in the world to connect satellite communications, to conduct field vital signs monitoring and rescue, and to explore healthy cloud services based on satellite communications.

LadyBird satellite series: LadyBird-1 is a 100 Kg satellite for the IoT. The other satellites are CubeSats: LadyBird-2 "Elvis Presley Star", LadyBird-3 "Hua Mi Star", LadyBird-5 "Linda Education Satellite” (equipped with remote sensing cameras, open data resources for primary and secondary schools, and is used for aerospace science education), LadyBird-6 “Tmall International Star” (equipped with a special material Tmall Dolls, as well as confession voice files of some Tmall users, which will be returned to the ground in the near future. This satellite is also the beginning of cooperation between Nine-day MSI and Alibaba), LadyBird-7 “RE: X Star” (is a public welfare satellite in cooperation with Luhan Studio).

Sagittarius-01 "model satellite adopts the "one-star dual-core" system structure, equipped with the second-generation on-board AI platform designed and developed by our team. The image processing capability is more than 1000 times that of the same weight satellite. It is the first high-performance satellite independently developed by Guoxing Aerospace. It is arguably one of the most 'smart' commercial satellites in the world."

Hua Mi Xing (华米星)
LadyBird-3 "Hua Mi"


Since there are only 13 objects cataloged (12 satellites + upper stage) and since they nearly have the same name, aren't they finally the same satellite ?

What about Weina 1C ?

Thanks for the (sort-of) live coverage, Steven!

That's 1-for-3 so far on worldwide launches on UTC December 7.

Q: Has "live" coverage of a launch, etc. ever been delayed by multiple minutes before?  Or is this a first?

I don't remember ever being delayed so long. Typical maximum delays I have seen is about one minute. Note that the launch was shown live in China!

Don't know if this was onboard but the three birds of this name are from three different producers and, I believe, the name itself is a delusion.
This message reflects my personal opinion based on open sources of information.
