Sich-2 (German: Sitsch ) is an earth observation satellite of the Ukraine .
On August 17, 2011 at 7:12 UTC it was brought into low- earth orbit from the Jasny Cosmodrome with a Dnepr rocket together with NigeriaSat-2 , NigeriaSat-X , RASAT and EduSAT .
Sich-2 is the third satellite among Ukrainian satellites named Sich. The first Sich-1 satellite was launched into orbit by a Zyklon-3 rocket in August 1995 . It was based on the former Soviet Okean- 1 remote sensing satellite and was the first Ukrainian satellite to be launched since the collapse of the Soviet Union. The first Chilean satellite FASAT-Alfa was supposed to be carried piggyback by Sich-1, but the separation failed. The second satellite Sich-1M was launched on December 24, 2004 with a Zyklon 3 rocket, but due to an error in the upper stage of the rocket, it entered an orbit that was too low of the planned three years.
The three-axis stabilized satellite is equipped with cameras in the optical (0.51 - 0.9 µm) and infrared (1.51 - 1.70 µm) range and is intended to provide images for agricultural and construction planning, mapping and monitoring of natural disasters. The swath width of the cameras is 46 km in the optical and 55 km in the infrared range. The resolution is about 8 m in the optical and 46 m in the infrared range. The images are transmitted to the ground station in the X-band , while the satellite is controlled via the S-band . The satellite is equipped with GPS receivers, magnetic gateways and a star sensor for stabilization . It was built on the basis of the MS-2-8 satellite bus for microsatellites from the Jushnoje Design Bureau and has a planned service life of five years.
