Cross-post:
December 11 - CZ-3B/G2 - XSLC, LC2 - Alcomsat-1
[..]
December November (?) - CZ-3B/YZ-1 - XSLC, LC2 - Beidou-3MEO3; Beidou-3MEO4

November 27

If the Beidou launch is slipping into December, will Alcomsat be able to hold that date? I seem to recall the minimum pad turnaround at Xichang is 2-3 weeks, unless that has decreased in the last few years.

The rumors that I have seen put the BDS launch in late December, after Alcomsat.

Given no other information, such as a satellite or launch vehicle processing delay, can we therefore deduce that this launch could happen as early as December 24-31?

(Awaiting news to support--or not--the deduction.)

The launcher is already known to be at XSLC, but I agree. Chances are slim to fly it before the end of the year.

Given:
There are reports that the launch yesterday is SAST's last in 2017. This essentially confirms that the GJ-1 launch has (as expected) slipped into 2018 and (barring extreme low probabilities of a CZ-2C slipping into the queue at TSLC) leaves just the Xichang launch next week for 2017.

And it has been officially confirmed that the YG-30-03 launch is China's last one of 2017.

And given:
China launches in 2017 (times in UTC)

BTW, these two CAS built satellites might not be called "M3 & M4" - there's a TV news report after last November's BDS launch interviewing the satellite production facility in Shanghai, and the two satellites about to be shipped back then was marked as "M7 & M8". Perhaps the satellite numbers were issued in blocks.... (come on BDS office, tell us which is which!  >:()

As the first pair was known as MEO-1/MEO-2 on official video (reference), I propose to call this one MEO-3/MEO-4 to be consistent

Here's the evacuation notice at the 1st stage drop zone (Tiandeng county, Guangxi) that confirms the launch is still on (and that the launch code is 07-82). Launch time is "7:10-ish am" = 23:10-ish UTC.

Nothing yet found here.....but it's early morning in China and I expect college students to rush out of their dorms when that happens  ;) (which happened in a previous launch out of Xichang).

A note for all direct insertion launches for navigation satellites - don't expect launch success confirmation until 4 hours after launch.  ;)

China sends twin BeiDou-3 navigation satellites into space
http://www.xinhuanet.com/english/2018-01/12/c_136890332.htm

XICHANG, Sichuan Province, Jan. 12 (Xinhua) -- China on Friday sent twin satellites into space on a single carrier rocket, as part of efforts to enable its BeiDou system to provide navigation and positioning services to countries along the Belt and Road by the end of 2018.

The Long March-3B carrier rocket took off from Xichang Satellite Launch Center in the southwestern province of Sichuan at 7:18 a.m.

This is the first launch of the BeiDou satellites in 2018, which will see intensive launches throughout the year.

The twin satellites are coded the 26th and 27th satellites in the BeiDou Navigation Satellite System (BDS).

Is it wise to stand so close to a burning hypergolic booster?
I guess the locals are just going to have to get use to this as a regular occurrence. What is it another 7 launches of this type of MEO satellite pairs to go?

:drumrolls: http://tv.cctv.com/2018/01/12/VIDEPenPlOWCqLqxkzy2AeBH180112.shtml  ;)

According to CAS today they have 8 navigation satellites going up this year, so I guess the CAST/CAS satellite distribution will be 10:8 by IOC; an earlier source indicates that CAS will build 10 of the Medium Earth Orbit satellites, making the final distribution 14:10.
The first 6 CAS satellites are apparently given numbers MEO-7 thru 12.

Oh I think the Chinese are a bit embarrassed by this kind of stuff, which is why they are gradually A) shifting more launches to Wenchang and B) use kerolox and hydrology with CZ-7 family launchers.

But it takes time... and they aren’t moving any faster than they have to.

There is some confussion in the designation system for BD-3 series. The CCTV footage is naming the satellites MEO-7 and MEO-8.
Some other sources call the mission on Jan 12th  Beidou-3 MEO-2 (http://www.chinanews.com/gn/2018/01-12/8422498.shtml) but the satellites itself Beidou-3 M7 and BD-3 M8 (http://www.xdkb.net/index/article/2017-12/06/content_1076624.htm). The mission designation for the Nov 5th 2017 launch is correspondingly Beidou-3 MEO-1 and Beidou-3 M1 / BD-3 M2 for the satellites .

Could 7 and 8 also be the space vehicle number of the spacecraft and ended up flying before 3 and 4?? think GPS SV number versus block number.
