KazSat

from Wikipedia, the free encyclopedia

KazSat ( Russian КазСат , Kazakh ҚазСат ) is the name of a number of Kazakh communications satellites .

KazSat 1

KazSat 1 , originally - before there were any plans for a successor - also just called KazSat, is the first Kazakh satellite to be launched on June 17, 2006 at 10:44 pm UTC (June 18 local time) with a Russian Proton-K / Block -DM3 - carrier rocket from Baikonur was launched into space.

KazSat 1 is a geostationary communication satellite built by the Russian space company GKNPZ Khrunichev , which has 12 transponders in the Ku band and is to be positioned at 103 ° East. The satellite is based on the " Jachta " satellite platform (Russian Яхта , English Yakhta ), making it the second satellite to use this platform after Monitor-E1 . The launch mass of the missile, which is relatively small for today's communications satellites, is 1,092 kg, the payload 180 kg, with an electrical output of 1.3 kW. The planned service life is 12.5 years. The drive system for orbital maneuvers and attitude control consists of a SPD-70 - ion thruster , which with xenon operates, and a K10K - cold-gas engine .

The contract to build and launch KazSat 1 with a volume of 55 million US dollars was signed in January 2004 . Initially, it was planned to launch KazSat 1 together with an Express AM satellite on a Proton M / Bris M rocket in December 2005 . However, it was later decided to launch KazSat 1 individually and on a slightly weaker and cheaper Proton-K / Block-DM. When problems arose with the Monitor E1 satellite shortly after its launch in August 2005, the launch of KazSat 1 was postponed by several months to mid-2006 in order to have time for further ground tests. The start was initially scheduled for June 8, but later had to be postponed to June 18 so that the Russian and Kazakh heads of state ( Vladimir Putin and Nursultan Nazarbayev ) - who are visiting Baikonur on that day - can attend the start.

On November 26, 2008, ground control lost contact with Kazsat-1, as a result of which the satellite was classified as a total loss due to an error in the "Control Engine Wheels" KUDM.

KazSat 2

After the first KazSat satellite was successfully launched, there were talks about the successor KazSat 2 . On September 25, 2006 it was announced that this satellite will also be built by GKNPZ Khrunichev. The contract was worth 115 million US dollars and started on July 15, 2011.

KazSat 3

The first phase of a tender for the development of KazSat 3 was completed in January 2011. According to the Kazakh authorities, there were offers from France, Germany, Japan, Russia, the USA, Israel and India to develop the spacecraft.

During the Paris Air and Space Show in Le Bourget on June 20, 2011, an agreement was signed with the Russian ISS Reshetnev to build the KazSat-3 satellite . The satellite is scheduled on the Ekspress-1000NTA - satellite bus built by ISS Reshetnev. It will start on April 19, 2014. The planned position is 58.5 degrees east longitude and the planned lifetime is 15 years. It is equipped with 28 Ku-band transponders and offers 5.5 kilowatts of power for its payload. The communications payload was provided by Thales Alenia Space.
