An unspecified satellite will be orbited by the Long March-2C (Y29) rocket from the Xichang Satellite Launch Center.

Launch rumored in May 2017.

rocket to begin stacking very soon I'm told. No details as to payload and pad but very likely going from LC-3

I believe this will be the first CZ-2 series launch from Xichang since Shiyan 2, also on a CZ-2C, in November 2004

Shijian Weixing 2 was the precursor to the Shijian-11 series of SIGINT satellites.   Could the new launch be a Shiyan Weixing that will be a precursor to the next generation SIGINTs?

We have had Shiyan Weixing 7 but not SW 6 yet .......... ?

Evidently we think alike.

Assuming no unidentified suborital or failed launches, there have been ten previous CZ-2 launches from Xichang; seven CZ-2E missions between 1990 and 1995 from Pad 2, and three CZ-2Cs in 2003-04. The first CZ-2C - Tan Ce 1 - definitely used the old Pad 3 (http://sci.esa.int/double-star/34513-launch-of-double-star-1/). The other two carried Shiyan 1 and 2 respectively - I do not know which pad they used. Whichever was the last to fly from Pad 3 would have been the final launch from the old pad before it was demolished and rebuilt.

Both from old Pad 3 which in fact was known then as Pad 1.

CALT did take the rocket out for a (dry) dress rehearsal at the pad between April 14 and April 28 though: http://www.calt.com/n689/c8373/content.html

I really wonder the reasons of flying the 2C from Xichang right now - last time it happened in 2003-4 1 of the launches was to a high EEO and the 2 polar orbit launches were at a period where I believe they had no other active pad that can be used (Taiyuan was out for maintenance and Jiuquan's new satellite pad was only coming online around that period). Either the payload's going to a high orbit (or a low inclination LEO), or the pads at other sites are booked full/out for reconstruction/maintenance......  ::)

BUMP:
LC3 is still configured for CZ-2C launches/testing at this time so next CZ-3 family launch likely to fly from LC-2 again. A CZ-2C launcher (training or flight version unknown) is still present at XSLC.

There were rumors that the rocket was actually brought back to Beijing in May/June after the fit checks, so it's not going to launch anytime soon.

Heh no wonder it's that hard to know what is flying - it must be yet another it-must-not-be-named thingy!  :-X

Since Yuan Wang 3 is now in the South Pacific (southeast of Fiji), IF this is really what will launch next week, a low inclination BLEO target orbit (GTO et al.) is more likely.

So what's that?  :-X

The rocket would have to take a 90 degree turn to match that from Xichang.....  ;D

Apparently, the Launch about this NOTAM will come from TSLC.
Last time I checked up 9ifly, they gave a time frame for this CZ-2C launch: 29th around noon

yes, which is what Chinasat-9A is. 07-78 was skipped when 07-79 was launched and 07-78 is expected with this CZ-2C flight.

Note that there is already a YG-30 launched in May 2016. It could be merely a muddling water designation, but it could also show some kind of relationship with that one.

Will be interesting to see what orbit do they end up with.....

Maybe the Chinese screwed up with the numbering system or mis-translated it into western numbers, and it should be Yaogan Weixing 31A, B and C?

I think this might be likely. I am not sure, if the triplet is on this single launch vehicle or if there will be three launches for three satellites. Lets see, how many objects will be tracked.

Yeah the announcement of the Chinese Academy of Sciences' Small Satellite Center as the contractor of the satellites and the emphasis on "electromagnetic environment research" points further away from linkage with YG-30 (the latter was built by CAST/DFH and was announced to be for "land survey/disaster relief" usage). ;)

If these were imaging satellites then the obvious answer would be "ground resolution".

Janes Defence article on this launch.

Quote
While official statements following Chinese satellite launches usually ascribe functions such as scientific research, land resource surveys, crop yield studies, and disaster relief, the Yaogan satellite series is assessed to include high-resolution optical imaging sensors, synthetic aperture radars, and electronic intelligence (ELINT) sensors for intelligence, surveillance, and reconnaissance (ISR).

The latest satellites appear to have been deployed as a triplet group, which is similar to the Yaogan 16, 17, 20, and 25 satellites, which were also deployed as triplets (for example Yaogan 16A, 16B, and 16C).

Their function is assessed to be for ELINT in support of maritime surveillance, not only in terms of detecting transmissions from a ship's radars but also for providing geolocation of the emitter by measuring the time difference in arrival of the intercepted signals at each of the satellites.

Right now the triplet is over a region of particular interest concerning ship movement...

Apparently Space-Track has reserved #42949 for 2017-058E/"CZ-2C DEB"

Months after rocket failure, China sends spy satellites into space
Chinese military’s three new probes will form a constellation to ‘monitor electromagnetic signals’

China successfully put three new reconnaissance satellites into orbit using a Long March-2C rocket on Friday – its first launch in nearly three months.
All launch activities had been put on hold after two failures in June and July that have delayed Beijing’s ambitious space programme, which includes lunar exploration.
The three Yaogan-30 satellites were launched from a centre in Sichuan province. They will join a larger probe launched in May last year to form a constellation to “monitor electromagnetic signals” and other unspecified missions, state news agency Xinhua reported.
The satellites are capable of intercepting radio signals from communications on Earth. They could also pick up the electromagnetic pulses generated by a nuclear explosion to gather intelligence after a thermonuclear weapon test, according to scientists.
But the mission and technical details of the satellites was not disclosed.
“These are military assets – they are not for civilian use, there’s no access,” said Li Xiaoming, a researcher at the Institute of Remote Sensing and Digital Earth at the Chinese Academy of Sciences in Beijing.
The Yaogan satellites are owned and operated by the People’s Liberation Army. The Chinese military has carried out more than 30 launches of the satellites since 2006, according to state media reports.
In the past, official announcements have listed civilian applications for the probes such as land use analysis and disaster relief, but this time there was no mention of any civilian uses.
They were developed by the Micro-Satellite Research Institute at the Chinese Academy of Sciences in Shanghai, according to Xinhua.
They are “just the first batch” of a number of similar satellites being developed for a planned global surveillance network, according to a researcher familiar with the project.
Equipped with cutting-edge sensors, the small satellites orbit the Earth in large numbers and at relatively low altitudes – meaning they can take continuous, high-definition images and pick up extremely faint signals, a job previously done by bigger satellites, the researcher said.
China was also developing large reconnaissance satellites, the researcher said, some of them equivalent to the biggest spy satellites of the United States.
But problems with the Long March rocket have delayed their launch.
The new Long March-5 heavy-lift launch vehicle lost power and plunged into the Pacific Ocean in July, taking with it China’s largest communications satellite.
That came just weeks after the unsuccessful launch of the Long March-3B due to a technical glitch in June.
Tian Yulong, secretary general of the China National Space Administration, told an international space conference in Beijing early this week that they had yet to determine what went wrong during the July launch.
Chinese space scientists and engineers have identified the cause of previous failures within weeks and sometimes hours of the malfunction. This time, months on, the authorities have yet to provide any details.
More than 80 per cent of the technology used in the Long March-5 – China’s biggest and most sophisticated rocket – was new, according to state media reports.
Tian said the team hoped to determine the cause of the problem by the end of this year. All space flights requiring heavy-lift launch vehicles would be delayed, including its mission to build a space station, he added.

Thus the connection between Yaogan 30 and Yaogan 30-01 is clarified !

Objects A and C has maneuvered relative to B. Difference in heigths is some 7 km now.

Well, it occured that this is not a triplet but three separate spacecaft. As of today, they are positioned along the orbit and separated by 120°.

This is still the case to-day
