Sterch

Sterch ( Russian Стерх for barn crane ) is the name of a new Russian satellite-based search and rescue system that is to replace the previous Nadezhda system.

It is part of the international satellite-based search and rescue system COSPAS-SARSAT . In contrast to Nadeshda, Sterch does not contain a system for satellite navigation, as this is taken over by the GLONASS satellite and only a single SAR transponder. The cuboid satellites are therefore much smaller and lighter than their predecessors and can be launched as a secondary payload with other satellites. They weigh around 170 kg and are supplied with energy by solar cell booms with around three meters and 110 watts of power. The planned lifespan is five years.

The first satellite, Sterch-1 , was launched on July 21, 2009 on board a Kosmos-3M launcher along with a Parus communications satellite. The second Sterch-2 satellite was launched from Baikonur on September 17, 2009 .
