Bunlar stationary yörüngeye mi oturtulacak?

No, EO spy satellites are usually sent to Low earth orbit.

Turkey Seeks To Build Indigenous Satellite
After having spent more than $1 billion on satellite programs, Turkey will spend its resources on local industrial efforts

Turksat 5B is a broadband satellite that will operate in Ku- and Ka-bands. Its high-throughput satellite payload will provide more than 50 gigabytes per second of capacity over a wide coverage including Turkey, the Middle East and large regions of Africa. The spacecraft will have a launch mass of 4,500 kilograms and an electrical power of 15 kW. It is planned for in-orbit delivery in 2021.

The satellites will be built by Airbus in its U.K. and French facilities. Both satellites are planned for a service lifetime largely in excess of 15 years. Turksat 5A and Turksat 5B are the 57th and 58th Eurostar E3000 satellites ordered, and the 7th and 8th in the Eurostar E3000e version, respectively.

Turksat provides voice, data, internet, TV and radio broadcasting services through its satellites, covering a geographical area extending from Europe to Asia.

Also on Nov. 9, Turkey’s minister of transport, maritime affairs and communications, Ahmet Arslan, said the Turksat 5A and Turksat 5B satellites will be launched by U.S.-based firm SpaceX.

“Our friends decided to launch our satellites with the Falcon 9 rockets of Airbus’ subcontractor, SpaceX,” Arslan said.

Turksat officials say the contract to build and launch satellites will be worth about $500 million. For those two satellites, the local contractors are Aselsan and Turkish Aerospace Industries, or TAI. The local satellite, 6B, will cost Turkey 545 million liras (U.S. $141 million), according to officials.

In October the Turkish government chose Airbus to build the planned satellites.

Elon Musk, chief executive of American electric car-maker Tesla and aerospace company SpaceX, met Turkish President Recep Tayyip Erdogan in Ankara on Nov. 8 to discuss cooperation between Tesla, SpaceX and Turkish firms.

SpaceX plans a manned mission to Mars by 2024 and a rocket capable of carrying passengers from one continent to another in less than an hour.

Turkey in recent years has heavily invested in satellite capabilities. In December it launched Gokturk-1, a new military satellite that is “20 percent Turkish” and will help the country in its anti-terrorism efforts.

The Gokturk-1 is a high-resolution, optical Earth-observation satellite for civilian and military applications. It can scan high-resolution images (up to 0.8 meters) and features an on-board X-band digital imaging system to handle data compression, storage and downloading.

Security officials say the Gokturk-1 would be widely used in Turkey’s fight against the Kurdistan Workers’ Party, a Kurdish insurgency group also known as PKK who has been designated as a terrorist organization by Turkey, the United States and the European Union. The fighting with the PKK has claimed nearly 40,000 lives since 1984 when the group launched a military offensive for a Kurdish homeland.

Having already spent more than $1 billion on satellite programs, Ankara wants to “nationalize” the satellite business. The Turkish government aims to build the first fully indigenous Turkish satellite by 2019. The country wants to invest more on “software, design and platform.”

Key local players in the ambitious satellite programs are military electronics specialist Aselsan, Turkey’s biggest defense firm; Tubitak Uzay, the state’s scientific research space department; TAI; and CTech, a software company.

Turkey wants to be operating a fleet of 10 satellites by 2023.

In 2015, TAI launched a $112 million Space Systems, Integration and Test Center where more than one satellite of up to 5 tons can be assembled, integrated and tested.

The Turkish government also is planning to launch its own space agency.

These are the last satellites to be manufactured by a non-Turkish company. Starting from Turksat 6A, all our future communications satellites will be made in Turkey.

https://www.tai.com.tr/en/project/turksat-6a

The project contract regarding to development and manufacturing of "TÜRKSAT 6A National Telecommunication Satellite" has been signed in an official ceremony on 15 December 2014.


The satellite program, that will be fulfilling the requirements of Turkish Satellite Operator Company TÜRKSAT, will be coordinated by The Scientific and Technological Research Council of Turkey (TÜBİTAK).


The financial budget for the program has been granted by Ministry of Transportation, Communication and Maritime Affair, TÜRKSAT and TÜBİTAK. TÜRKSAT 6A as the first indigenous telecommunication satellite of Turkey, has planned to be developed in cooperation with national industries and institutes with a work share model based on supplementary competencies of the participants.


With TURKSAT 6A, it is planned to convey know-how and expertise acquired from indigenous earth observation satellite projects to communication satellites. Within this scope, design and manufacturing work packages according to Satellite Structural, Thermal Control, Chemical Propulsion Subsystems, Harness and Mechanical Ground Support Equipments will be under TAI's responsibility. Additionally, TAI will co-develop Satellite On-Board Data Handling Software, Command & Control Software and Assembly, Integration and Test activities with TÜBİTAK Space.


The assembly, integration and test activities of TÜRKSAT 6A Satellite will be performed at the TAI's Facilities – Assembly, Integration and Test Center in Ankara.


The satellite is planned to be located in to 42°E geo-stationary orbit for the operation of National Satellite Operator Company, TÜRKSAT. The spacecraft will have a launch mass of more than 4 tons. The system will be designed to provide commercial services for at least 15 years.


TÜRKSAT 6A will bring extended capabilities and additional capacity for high and secure data transfer applications with:

• 20 Ku-Band transponders that can be operated simultaneously
• 2 X-Band transponders operating at full power.

Once again outdated wikipedia articles mislead me. The wiki article for Turksat 5A lists TAI as the manufacturer and doesn't even mention Airbus.
Thanks for the clarification.

Yeah, unfortunately we have a lot of outdated articles on Wikipedia. We should probably add it to the update list @Combat-Master made the other week.

It should be noted Turkish content ratio will be about 25% in Turksat 5a/5b. So We will integrate our local systems and gain more experience in this project. Tai is also working on smaller(1-1.5 tonnes) communication satellite. These projects are baby steps of our communication satellite vision.

Yes. We should also note that even with Turksat 6A, which will be the first domestically made Turkish communications satellite, we're not talking about 100% indigenous components. Even seasoned companies who have been building satellites for decades don't make all of their components. Instead, a lot of them are outsourced from global suppliers. (Microchips, PCBs, memory modules, processors, radiation shielding, thrusters, solar panels, antennas/transponders, batteries, etc etc.)

In a similar fashion, TAI will design and perform the final assembly of Turksat 6A in Turkey, but it is sure to bear many outsourced components and subsystems. And that is normal! It's what every other aerospace company does. What I'm curious about the most is whether Turksat 6A will feature a domestically made "satellite bus" or license another company's design instead.

Guzel de bombos hertaraf. I can hardly wait to see those facilities filled with satellites, probes, space capsules, rocket parts under construction.

 

[Pax Ottomana]

Hmm. Apparently it only takes 4 satellites to create a small, "low accuracy" GPS system. Can't we use this cheap cubesat 3U architecture (10x10x30cm) to create a low-cost national GPS system? According to this source, 4 of these can't cost more than $2 million, including cost of launch.

Or is it too small/underpowered for GPS signal purposes?

Roketsan developing nozzle gimbal thrust vectoring, this might be more geared towards Ballistic Missile development

 

[Silahtar]

...The development project for a satellite propulsion system, called „ÜMIT“ for short, is intended to fill this gap...

Roketsan developing nozzle gimbal thrust vectoring, this might be more geared towards Ballistic Missile development

This is a major development and shows serious progress toward an actual SLV. I'm curious though, is Roketsan or another company also developing a first stage and second stage engine for this? And also investing enough resources into the production and storage facilities of cryogenic (super-cold) substances like liquid hydrogen (fuel) and liquid oxygen (oxidizer)?
