Ha! That would be interesting, to get to know something about a piece of
Russian (Glonass) technology!
But also read a paper by V.B. Nepoklonov about obtaining geodetic earth
I found a copy at
See Table 2 on page 7 for some WGS84 - PZ90 (almost the same as SGS85)
See also reference 7 (Mirsa, Abbot) in this paper; can't find a (free)
Mirsa P.N., Abbot R.I. SGS85-WGS84 Transformation // Manuscripta Geodaetica.
1994. Vol. 19.
