Yes, my link was also on Zhuklino site. Seems like you are right, active site is NE-1. Pavel Podvig also thinks the same.

As for SW-1a. Now I see that Mr. Podvig is right, now there is satellite control centre here. But...
Compare the attached overlays. One from Serpuhov and one from Nudol site. (Actually, Nudol overlay should be mirrored from left to right, I can't do that in GE) And try to imagine, what could be here before. (Or planned to be)

If you interested in ICBMs, you can find links in this post.
