system. Unlike their predecessors, Sterkh satellites do not carry navigation systems, since this function has been taken over by GLONASS
. Sterkh satellites are smaller than their predecessors and were designed to be launched as secondary payloads with other satellites.
The satellites have a mass of 160 kg. Their overall dimensions are 750 x 1350 x 2000 mm in shipping condition, and 976 x 2957 x 10393 mm in operational condition, with opened solar panels and risen gravitational bar. The satellites incorporate the air-borne radio rescue complex RK-SM. They are expected to have an operational lifetime of 5 years. The satellites are designed and manufactured by Production Corporation Polyot
