The third launch of BeiDou-3 IGSO satellites.
-
Heads-up/cross-post; I guess we'll be able to determine the payload when the NOTAMs are released and/or if there are pictures of the LV (CZ-3B vs. CZ-2C) on the pad before launch.
9ifly Chinese space forum is reporting that the Yaogan Weixing-30-06 triplet will be launched in October.
This is actually more of a guess than anything else, as 9ifly now indicates that the next launch out of Xichang (mid-October-ish) will be for BDS-3 IGSO-3.
-
Launch at the end of October.
-
Launch now schedule for November.
-
The CZ-3B/G2 for this launch is already at the LC2 Launch Complex.
-
Launch around November 7 (?)
-
Still trying to confirm this, but there are reports that that this one might be launching later today GMT (!).
Air space closure notices are currently missing as of right now.

One source indicates a T-0 of 17:43 UTC.

China Aerospace puts it around 1700 UTC and has few launch pad pics https://www.weibo.com/5616492130/IeFDTvEJg

It should be launch time at Xichang. Waiting for the usual resports from locals...
-
Liftoff confirmed.

At 01:43 on November 5, 2019, China successfully launched the forty-nine Beidou navigation satellites with the Long March III B carrier rocket at the Xichang Satellite Launch Center. The successful launch of the satellite marked the completion of the launch of all three tilted geosynchronous orbit satellites of the Beidou No.3 system.
On November 5, 2017, the first star of Beidou No. 3 was successfully launched and successfully entered the track, opening a new era of Beidou system global networking. In the past two years, the 7 major systems of the project, more than 300 participating research units, and tens of thousands of scientific researchers have successfully completed 16 satellite launch missions and successfully completed 24 Beidou 3 network satellites and 2 A Beidou-2 backup satellite is sent to the scheduled orbit. At present, the construction of the Beidou No. 3 system has entered the final stage of the final battle, and six Beidou No. 3 network satellites will be launched in the future to fully build the Beidou global system.
The Beidou navigation satellite and supporting carrier rocket launched this time were jointly developed by the China Academy of Space Technology and the China Academy of Launch Vehicle Technology affiliated to China Aerospace Science and Technology Corporation.
This is the 317th flight of the Long March series of launch vehicles. (Photo: Liu Changlian, Liu Xu)

China launches new BeiDou satellite
Source: Xinhua| 2019-11-05 03:11:54|Editor: yan
XICHANG, Nov. 5 (Xinhua) -- China sent a new satellite of the BeiDou Navigation Satellite System (BDS) into space from the Xichang Satellite Launch Center in Sichuan Province at 1:43 a.m. Tuesday.
Launched on a Long March-3B carrier rocket, it is the 49th satellite of the BDS satellite family and the 24th satellite of the BDS-3 system.
It also marked that a total of three BDS-3 satellites have been sent into the inclined geosynchronous Earth orbit.
The launch was the 317th mission for the Long March series of carrier rockets.
The new satellites and the carrier rocket were developed by the China Academy of Space Technology and the China Academy of Launch Vehicle Technology, under the China Aerospace Science and Technology Corporation.
China will launch another six BDS-3 satellites to complete the BDS global network.

According to this list a CZ 3B/G3 was used.

That also lists as G3
2015.09.30 Beidou 20 (BD-3 I2-S)
2016.08.06 TT-1 01
2016.12.11 FY-4 01 (FY 4A)
2018.11.01 Beidou 41 (BD-3 G1Q)
2019.03.10 Chinasat 6C (ZX 6C)
2019.03.31 Tianlian-2 01
2019.04.20 Beidou 44 (BD-3 I1Q, IGSO-1)
2019.06.25 Beidou 46 (BD-3 I2Q, IGSO-2)
2019.11.05 Beidou 49 (BD-3 I3Q, IGSO-3)
which are not in Gunter's list at
https://space.skyrocket.de/doc_lau_det/cz-3bg3.htm
G3 has a 4.2 m diameter payload fairing and G2 has a 4.0 m diameter fairing. This reduces the GTO payload by 100 kg. I guess we can go back and count pixels to see if the above list is correct.

Satellite in Inclined Geosynchronous Orbit

I'm guessing the unexpected inclination of Beidou 49 is why US tracking didn't find it for 2 weeks... will be interesting to see if future launches go to the same 58.7 deg inclination.
