Hi All Today I was doing some research on SHIYUAN 2 which I copied on S-band exhibiting extreme fading indicating it was tumbling. Upon doing some research into this s/c I came across this Russian website: astroguard.ru On the site I came across a wealth of light curve data for classified satellites and others (except CIS) organized in an easily searched database. While digging in I found their monthly reports in Russian. The following report reveals something that I was not aware of in the western literature about the NOSS 3-x missions. The 'follower' has an ~ 2 second period which the author of this report attributes to a rapidly spinning antenna array or similar structure. The report can be found here and easily translated with Google. ftp://astroguard.ru/2017/reports/%D0%9C%D0%9C%D0%A2_2017_02.pdf Regards, Scott Tilley ROBERTS CREEK 1: 8049 ST 49.4348 -123.6685 40.
