TÜRKSAT 6A

TÜRKSAT 6A is Türkiye’s first fully domestic and national communication satellite. It was developed through a collaboration between TUSAŞ, ASELSAN, and CTech under the project management of TÜBİTAK UZAY. With a launch mass of approximately 4.2 tons and a 16-year operational lifespan, the satellite operates in a geostationary orbit at 42° East. TÜRKSAT 6A provides communication and broadcasting services covering large parts of Türkiye, Europe, Asia, and Africa, featuring more than 20 transponders across multiple frequency bands. The project was launched into space on 9 July 2024 aboard a SpaceX Falcon 9 rocket and was commissioned into service in April 2025. All operational processes are conducted via the domestic mission control software platform TStar-GO developed by TÜBİTAK UZAY.

The TÜRKSAT 6A project was initiated in 2014 with the goal of developing Türkiye’s first fully domestic communication satellite. The “TÜRKSAT-6A National Communication Satellite Project Agreement and Additional Protocol” was signed in the same year by the Ministry of Transport and Infrastructure, TÜBİTAK, and TÜRKSAT. By 2017, design and engineering work had reached completion, and production of qualification test models of the satellite had begun.

Between 2018 and 2022, the engineering model, thermal-structural qualification model, electrical-electronic model, and flight model were developed, and system-level tests were successfully conducted. In 2023, the integration process was completed, and launch preparations were planned to be carried out using SpaceX’s Falcon 9 rocket.

TÜRKSAT 6A was launched into space on 9 July 2024 from Cape Canaveral Space Force Station in Florida, United States, and conducted its first test broadcast on 17 February 2025. Following the completion of all system tests, it was officially commissioned on 21 April 2025 in a ceremony attended by President Recep Tayyip Erdoğan.

The TÜRKSAT 6A project was executed under TÜBİTAK’s 1007 Public Institution Research and Development Projects Support Program. It was funded by the Ministry of Transport and Infrastructure and TÜBİTAK, with TÜRKSAT A.Ş. serving as the end-user institution. The satellite was developed through collaboration between TÜBİTAK UZAY, TUSAŞ, ASELSAN, and CTech.

After the design phase was completed, the satellite’s engineering model (EM), thermal-structural qualification model (TSQM), electrical-electronic satellite model (EESM), and flight model (FM) were produced. System-level tests conducted on these models covered launch conditions and space environment simulations.

The majority of the software, hardware, and subsystems used in the development process were produced using domestic capabilities. The ground infrastructure was prepared to operate from the test and mission control centers established at the TÜRKSAT Gölbaşı Campus. Throughout the project, a workforce of engineers and a production infrastructure specialized in satellite technologies were developed.

TÜRKSAT 6A was launched into space on 9 July 2024 at 02:30 Türkiye time from Cape Canaveral Space Force Station in Florida, United States, aboard a SpaceX Falcon 9 rocket. The launch operation, delayed by approximately two hours due to weather conditions, was successfully completed.

Thirty-five minutes after launch, the satellite separated from the rocket, and its first signal was successfully received at the 65th minute, confirming communication with the ground control center. The first command was transmitted from the ground control center one hour after signal acquisition.

Following launch, TÜRKSAT 6A entered an elliptical temporary orbit with a perigee of 300 kilometers and an apogee of 70,000 kilometers. During this phase, the solar panels were deployed and power generation began. The satellite completed a four-stage maneuver using its chemical propulsion system to reach its final geostationary orbit at 42° East longitude.

Throughout the orbit insertion process, orbit determination, burn parameter calculation, burn command execution, and orbit control operations were conducted via the domestic mission control software TStar-GO. After all tests were completed, TÜRKSAT 6A was officially commissioned on 21 April 2025.

TÜRKSAT 6A is designed to provide long-term communication services with a 16-year operational lifespan and a design lifespan exceeding 22.5 years. The satellite was launched on 9 July 2024, conducted its first test broadcast on 17 February 2025, and was officially commissioned on 21 April 2025.

Orbit insertion, testing phases, and commissioning procedures were completed according to the planned schedule. All these processes were conducted via the domestic mission control software TStar-GO developed by TÜBİTAK UZAY.

Among TÜRKSAT 6A’s achievements are the successful deployment of Türkiye’s first fully domestically produced communication satellite, thereby placing Türkiye among the 11 countries capable of launching their own communication satellites. Additionally, the domestic subsystems and equipment developed under the project have reduced Türkiye’s dependence on foreign technologies in satellite systems and established a reusable infrastructure for future space projects.

The mission control activities of TÜRKSAT 6A are conducted entirely through the fully domestic TStar-GO mission control software developed by TÜBİTAK UZAY. From launch through orbit insertion, testing, and commissioning, all operations were executed via this platform.

The mission control system performs functions including satellite system management, orbit maneuver planning, and mission operation monitoring. Communication, command transmission, and data reception between the satellite and ground control centers are also conducted through the same infrastructure.

System operations are managed from control centers located at the TÜRKSAT Gölbaşı Campus. All software, hardware, and monitoring systems used in operational processes are domestically produced. This structure constitutes one of the key components reducing external dependency in satellite mission planning and execution.

TÜRKSAT 6A provides services across a wide geographic area encompassing Türkiye’s Western and Eastern coverage regions. The satellite expands the coverage of existing TÜRKSAT communication satellites to include countries such as India, Thailand, Malaysia, and Indonesia.

Through more than 20 transponders operating in different frequency bands, the satellite delivers television broadcasting, communication services, and data transmission. This coverage structure is designed to serve a population of approximately 5 billion people.

The satellite’s high power capacity and wide bandwidth capabilities enable uninterrupted television and radio broadcasting, as well as efficient implementation of data communications and broadband applications. Following its commissioning, TÜRKSAT 6A began providing infrastructure for the broadcast of 50 television channels via Sri Lanka’s Freesat Lanka platform.

The TÜRKSAT 6A project was executed internationally while maintaining Türkiye’s priority for domestic production. The satellite was launched into space from Cape Canaveral Space Force Station in the United States aboard a SpaceX Falcon 9 rocket. The launch process was monitored simultaneously by Turkish engineering teams at both U.S. and Turkish mission control centers.

Following its commissioning, a capacity agreement was signed between TÜRKSAT and Sri Lanka’s Freesat Lanka broadcasting platform. Under this agreement, 50 television channels are now broadcasting via TÜRKSAT 6A, aiming to transform Türkiye’s satellite capacity into an international service export.

These collaborations represent the first international commercial steps taken to provide communication and broadcasting services within TÜRKSAT 6A’s coverage area.
