@ Kairo - Isn't SAGG just a Russian expression for TVM (Track-via-Missile)?
@ Hpasp - for such lofted trajectory - is it similar to what the US have already invented for Nike-Hercules, and (solved in a slightly other way) combined guidance flight profile for Vega's 5V28? Was it intended to extend the missile range, and / or to improve its initial position to engage a maneuvering target (from above)?
SAGG is the US expression describing the Russian "TWM" guidance method.
Russians simply call the two guidance method used by the S-300P as proportional or combined.
(They are similar to the Vega)
