 The Fregat uses storable propellants (UDMH/NTO) and can be restarted up to 7 times in flight – enabling it to carry out complex mission profiles.It can provide three-axis or spin stabilization of the spacecraft payload.• Autonomous - carries the whole payload delivery process itself without any assistance from Earth 
• Smart - AI of the upper stage is programmed to avoid various emergency situations by its own algorithm 
• Precise - provides almost absolute delivery accuracy right into a target orbit, due to its navigation equipment based on Glonass and GPS 
• Multiple-start ability - engine can be restarted up to 7 times, which makes possible to ensure optimal delivery or to deliver multiple payloads on different target orbits 
• Versatile - fueled tanks are being loaded before installation in launch complex, which makes Fregat compatible to any launch vehicle 
• Active lifetime up to 2 days 
• Ability to start from four spaceports
