Sterkh

Sterkh was a Russian satellite-based search and rescue system, which formed part of the International Search and Rescue Satellite-Aided System (COSPAS-SARSAT).[1]

Overview

Sterkh was developed as a replacement for the older Nadezhda system. Unlike their predecessors, Sterkh satellites did not carry navigation systems, since this function had been taken over by GLONASS. Sterkh satellites were smaller than their predecessors and were designed to be launched as secondary payloads with other satellites.[2]

The satellites had a mass of 160 kg. Their overall dimensions were 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 incorporated the air-borne radio rescue complex RK-SM.[2] They were expected to have an operational lifetime of 5 years. The satellites were designed and manufactured by Production Corporation Polyot.

The first satellite in the series, Sterkh-1, was launched on 21 July 2009 aboard a Kosmos-3M carrier rocket along with a Parus.[3]

Sterkh-2 was launched on 17 September 2009 on a Soyuz-2.1b along with 7 other satellites.[4]

gollark: Heavpoot: how about functions with a linear type thing such that they can only be used once.
gollark: You could probably RLE them if it's a huge problem.
gollark: I generally wouldn't agree with vaguely dishonest things like that, and I don't know if anyone actually thinks that's the goal.
gollark: I suppose if you model LGBTQ+ etc. acceptance as some sort of 1D scale ranging from "persecuted heavily" to "worshiped as gods" with "general sensible acceptance" in the middle, and we're somewhere down between "persecuted" and "acceptance", then even if the target is "general sensible acceptance" it may be more effective to... market stuff? slightly more toward the "worshiped as gods" end in order to reach the middle.
gollark: Yes.
