According to 9ifly Chinese space forum, the launch team for this mission will arrive at Taiyuan the next weekend.

Offline Galactic Penguin SST

Latest reports puts this launch at around, or even behind the YG-16 launch (it was supposed to be half a month earlier than the YG launch when the satellite arrived at the launch site). That puts the launch date in mid- (perhaps late) November.

Offline Galactic Penguin SST

Reports from forum members monitoring blog posts of the launch team reports that the launch date could be on November 12 (after a little calculation with the 22 day nominal launch processing flow). Since the satellite is going for a SSO around the terminator (the local time and descending node is 06:00, according to here: http://database.eohandbook.com/database/missionsummary.aspx?missionID=465), this puts the launch at ~23:00 Zulu on November 11.

A second satellite on board is confirmed?

A second satellite on board is confirmed?

I believe that XY-1 is almost certainly confirmed to be launch on the same rocket. There are talks of even more payloads on this launch, but I can't confirm it at this stage.

Nope, and I have seen another version: launch on Monday GMT (Tuesday LT). Either way it's not within the next few hours, so enjoy the Arianespace show!  ;)

And nope, it doesn't look like it will launch today either, with zero news about the launch during the last few days.....  :-\

Edit: after finding quite a few blogs of the people working at the launch site, I am still not sure when the launch will come, but at least the preparations seems to be coming to a close soon. Oh and it surely looks cold there with the rolling hills completely covered with snow!  8)

Offline Galactic Penguin SST

According with the 9ifly Chinese space forum, HJ-1C launch is now schedule for November 19/20.

Not sure if this is correct.............. another source said that the launch date is a bit later than that, in late November. With the ZX-12 launch on November 22 and the YG-16 launch also pointing towards late November (the satellite trio were transferred to the pad yesterday), it should be interesting to watch next week!

In the meantime, here's a model of XY-1 displayed at the Zhuhai Airshow right now: (the strange structure of the satellite with two trusses hanging on either side hosting the payloads was apparently due to the tight space inside the payload fairing that it has to share with the big SAR antenna of HJ-1C, which also caused some of the original payloads to be dropped  ::))

What are the two other satellites left and right off XY-1?

I think the one to the right is SJ-9A, while the left one is the Electromagnetic Monitoring Test Satellite, currently still in design phase.

So, launch around 2300UTC. At this still no confirmation if the FN-1 satellites will be on board?

Probably, as there are reports of three satellites on board the rocket. Given that the two FN-1 satellites will not separate until after some time in orbit, I think it can bee seen as "one spacecraft", in the same way as the Japanese ETS-7 pair did.

Too early I'm afraid: the blogs entry should actually read "the launch at six-something hours"! The Sun is still roughly an hour away from rising, and if the launch was that early the satellites would face darkness for the next half an orbit! Look for launch indications between 22:45 and 23:00 UTC.  ;)

We don't have any idea of the size or mass of XY-1, right?

It uses the CAST150 (= CAST300 = CAST1000C, even the Chinese are having fits on the ever changing satellite platform name  :-X) satellite platform, so maybe 150 kg or so? I think the mock-up I posted earlier may well be a 1:1 model.

    By the way, I've seen 160 kg for FN-1A but I think that includes the 30 kg FN-1B, so after separation I'm guessing it's only 130 kg.

    We don't have any idea of the size or mass of XY-1, right?

    The LinkedIn page of an engineer who worked in this satellite gives a mass of 140 kg.

    Great - and that data seems to be 2011 so the mass probably didn't change too much between then and launch. Thanks!


    This source puts the mass at 129.9 kg: http://www.9ifly.net/forum.php?mod=redirect&goto=findpost&ptid=10495&pid=229167

    Hmm that link doesn't work for me.

    SpaceTrack has now reassigned the cataloged objects so new TLEs are 38997 HJ, 38998 FN, 38999 XY, 39000 rocket stage.

    HJ-1C has started transmitting radar data to the ground yesterday, with pretty good results. (source:http://www.cresda.com/n16/n1100/n1310/182226.html)

    A bit of clarification: originally the plan was to source the mesh antenna and the microwave emitter from Russian sources, but the plan later fell through after the Russians were reluctant to hand over the products and export licenses. In the end the Chinese gave up and developed both of them by themselves (the microwave emitter with the 14th electronics institute of CAS since Oct. 2008 and the antenna with CAST's Xian sub-division since Feb. 2010), which explains the huge delay with the development of it. I don't know if the Chinese built them with access to those Russian blueprints though..........

    It is now almost 4 months since the launch of Fengniao 1 (Hummersat)
    but I haven't heard any discussion of the separation of the 1A sub-payload for the formation flying mission, and
    no suitable object has been cataloged. Does anyone have any news?

    I recently looked at the orbital data for HJ-1C. On 2014 Jan 15-17 it lowered its orbit from 474 x 487 km to 423 x 467 km.
    Then, after a year in the decaying lower orbit, on 2015 Feb 5-9 it raised orbit again from 395 x 414 km to 439 x 460 km.
    The new orbit matches the altitude HJ-1C would have decayed to if no low orbit phase had occurred; it also
    is close  in height (but not ultraclose, and in a different plane) to the orbit of object C, identified as XY-1 by Space-Track.

    The attached plot shows the orbital period vs time for objects A (blue), B (red) and C (green).

    Unless I've missed a discussion in another thread, I don't think I've seen an explanation of this.

    Oh, and still no report on Hummersat 1B or evidence of it having separated.

    I can't recall the source, but there was an antenna problem that gave lower resolution, so the orbit was lowered to regain the planned capability.

    Ah, I did hear about the antenna problem.  BUt then raising the orbit again - does that mean they fixed the problem I wonder?

    They've only raised it slightly above the altitude they lowered it to, not up to the initial altitude, so I'd guess no.

    Makes sense, just a reboost. I was led astray by how well the new curve follows the previously predicted decay curve.

    If it did, it wasn't catalogued.  The debris objects are in different orbits, most likely LV retro covers.

    Launched in 2012, the experimental Chinese satellite Xinyan-1 [XY-1, NewTech-1] (38999 / 2012-064C) burned out in the atmosphere. This follows from the North American Aerospace Defense Command, NORAD. The device left orbit on Saturday. The last time was recorded by means of observation on the night of October 5, then it burned down in the region of South Africa.
