KazSat 2 is a commercial communications satellite operated by the Kazakh National Space Agency.

It was placed in geostationary orbit by International Launch Services (ILS) on July 15, 2013 at 23:16:00 UTC with a Proton-M launcher from launch site 200/39 in Baikonur together with SES-3 . The three-axis stabilized satellite with 20 Ku-band - transponders (of which serve twelve for communications services, four for television broadcasts and four in reserve) fitted and should supply from the position 86.5 degrees East, customers in Kazakhstan and Central Asia with a range of telecommunications services.

After the first KazSat satellite ( KazSat 1 ) was successfully launched in June 2006, there were talks about the successor. On September 25, 2006 it was announced that this satellite will also be built by GKNPZ Khrunichev . The order volume is 115 million US dollars; the start was scheduled for 2009 when the order was placed, but did not take place until July 2011. According to the head of the Kazakh national space agency and former cosmonaut Talgat Mussabaev , the Russian manufacturer made extensive compensation payments to Kazakhstan for the program delays . KazSat 2 is based on the Russian Jachta satellite bus , in which the satellite components are mounted around a cylindrical, load-bearing structure, which enables a double start with the SES 3 on top. In contrast to the failed predecessor KazSat 1, components from Western Europe were used to a greater extent in the production, which repeatedly suffered delays. The sensors were used to determine the position and motion of the satellite from EADS Astrium and subsidiaries of the group. The communication payload also has Western European origins, as Thales Alenia Space helped with the development, as with KazSat 1 . The payload weighs 215 kilograms and has an energy requirement of around 1.8 kilowatts. The energy supply is provided by two solar cell arms. The satellite, which weighs 1,272 kilograms when it is launched, has a target total service life of 14.5 years.
