Türksat

from Wikipedia, the free encyclopedia

Türksat is a Turkish satellite and cable network operator and the name of a number of Turkish communications satellites . These are currently being looked after by Aérospatiale and the company Türksat Uydu Haberleşme Kablo TV ve İşletme A.Ş., which operates under the name of the satellites. (in German: Türksat Satellite Kommunikation Kabelfernsehen und Betrieb AG), often shortened to Turksat AS Satellites of the new generation from 4A (from 2014) are exclusively managed by Turksat AS . According to its own statements, the company plans to operate a total of 7 satellites by 2019 and to become one of the world's 10 largest satellite companies by 2023 (100th year of the founding of the Turkish Republic). In addition to the satellites bearing the name Türksat , the operator will also use the Eutelsat 33A satellite , which will be relocated from 33 ° East to 31 ° East for this purpose.

Türksat-1 series

The Türksat-1 satellites are based on the Spacebus-2000 satellite bus and are equipped with 16 transponders in the Ku band (11 to 14 GHz). Ten of them have a bandwidth of 36 MHz and six of 72 MHz. Its take-off mass is around 1750 kg and the planned lifespan was ten years.

Türksat 1A

Türksat 1A was the project's first satellite and was to be launched on January 24, 1994 by an Ariane 4 from the Center Spatial Guyanais . However, due to a failure of the launcher, it exploded before the satellite reached its orbit.

Türksat 1B

After the loss of the Türksat 1A, the Türksat 1B was successfully moved to the 42 ° East position on August 11, 1994 . After a few tests, it was officially put into operation on October 10, 1994. It serves three different areas (Turkey, Central Europe and Central Asia) with television and radio, data and telephone transmissions. Four of the transponders can be switched between Turkey and Central Europe and three between Turkey and Central Asia.

Türksat 1C

After the loss of Türksat 1A, Aérospatiale began building a replacement satellite under the system's insurance terms. By changing the contract with Aerospatiale, the satellite was modified in order to be able to supply two additional large areas. This made a direct connection between Europe and Central Asia possible via the satellite.

Türksat 1C was successfully brought to a position of 31.3 ° East on July 10, 1996. After completing tests, it was then moved to its final position of 42 ° East (which took a total of 17 days), where it took over the transmissions from Türksat 1B. This was then brought to the starting position of Türksat 1C. Türksat 1C transmits analog and digital television and radio programs and continues to transmit telephone calls (Central Asia IBS) and data connections (VSAT) in the Central Asian region.

Türksat 2A / EurasiaSat 1

For the Türksat satellite system, there was soon a need to provide new satellites with more channels, greater coverage and backup capabilities such as that offered by other satellite systems on the international market. In order to cover a larger coverage area for local customers and to compete with other satellite operators, the next satellite should be positioned at the same location as Türksat 1C. The Turk Telekom founded therefore a joint venture company called Eurasiasat with Aerospatiale (later merged with Alcatel Space), which with the purchase of a new generation of satellites called Turksat 2A / Eurasiasat one was commissioned.

The result was Türksat 2A, which started its service on February 1, 2001 at the same position 42 ° East as Türksat 1C. The satellite is based on the 3000B3 satellite bus and has a launch mass of 3535 kg. It has 34 high-performance transponders, 22 of which are fixed to the same two areas as Türksat 1C and have a bandwidth of 33 MHz. The remaining twelve transponders with a bandwidth of 36 MHz can be aligned to two different reception areas.

Türksat 3A

In February 2008, Alcatel Alenia Space announced that they had transported the Türksat 3A satellite to its launch site in Kourou, French Guiana . The new satellite replaces Türksat 1C and made it possible to cover larger areas than before with telecommunications services and television broadcasts. With the help of switchable transponders, Türksat 3A also functions as a bridge between Europe and Asia.

The satellite is based on the 4000B2 satellite bus from Alcatel Alenia Space and has 24 Ku-band transponders (twelve with 36 MHz and twelve with 72 MHz bandwidth) and an output of around eight kilowatts. Its takeoff weight is around 3060 kg and it was stationed at 42 ° East .

The launch of Türksat 3A with an Ariane 5 was originally planned for May 30, 2008, but due to a software error in the launcher, the launch was delayed somewhat. However, it was then successfully launched into orbit along with Skynet 5C on June 12, 2008 .

Türksat 4 series

Türksat 4A

This satellite at the known position 42 ° East was launched on February 14, 2014 at 21:09 UTC with a Russian Proton-M / Briz-M launcher from the Baikonur spaceport in Kazakhstan. Unlike the previous satellites, this model was jointly produced by 14 Turkish and several Japanese engineers and is based on the DS2000 platform from Mitsubishi Electric . The takeoff weight is 4,850 kg, the bandwidth is 2,084 MHz. On the night of September 18, 2014, the satellite was officially put into operation after longer test phases at 50 and 42 ° East. The reception parameters of practically all channels on all three satellites at 42 ° East were changed, so that a complete channel search and the reorganization of all channels found is necessary.

The cover exceeds the previous models many times over. In addition to extended reception with smaller antennas in Europe and Asia in the FSS C-band, reception from all over continental Africa in the Ka-band is possible.

Türksat 4B

This satellite is identical to Türksat 4A and is to be placed at 50 ° East . The launch took place on October 16, 2015.

Other planned satellites

  • Türksat 5A is scheduled to start in 2020 and is intended for use at 31 ° East .
  • Türksat 5B is planned for 2021.
  • Türksat 6A is planned for 2020.
