2 objects have been catalogued by USSTRATCOM:
2014-066A/ 40286 in 687 x 705 km x 98.22° (presumably the S/C)
2014-066B/ 40287 in 673 x 690 km x 97.96°
Earlier in this thread or maybe in the SJ 11-7 thread it was said that this would be the final launch in the series. I wonder what will replace what seems to be an important group of satellites.
A prototype of the SJ-11 series spacecraft was launched as SY-2 which also introduced the CAST2000 platform. It was known that SY-2 has the (secret ?) designation QS-1. QS stands for Outpost (Qiánshào; 前哨), which is likely the designation for the whole satellite based missile early warning program. 2013 saw the introduction of the CAST3000 platform by SY-5. At least one source has told that this was QS-2. So maybe in the near future we will see the first operational flight, very likely within the SJ-series.
Hmm....
this article (
about one of the chief designers of the payload system on SJ-11) that was only dug out recently seems to unambiguously pointing to SJ-11 being ELINT related, with sprinkles of mentioning of signal detection here and there.
I suddenly remember that the French have similar small ELINT satellite constellations - ESSAIM and ELISA. Maybe they serve a similar purpose, but with 4 operational orbit planes?
