The first and only Space Systems Assembly, Integration and Test  (AIT) Center of our country, which exist in a few developed countries leader in the space sector in the world, was established at TURKISH AEROSPACE Facilities within the scope of GÖKTÜRK-1 Program.

Established with the investment of the Presidency of the Republic of Turkey Undersecretariat for Defense Industries (SSB) and Ministry of Transport and Infrastructure & TURKSAT A.S., and being operated by TURKISH AEROSPACE, this state-of-the-art AIT center is enable assembly, integration and test activities of more than one satellite up to 5 tons simultaneously by means of 3.800 m2 ISO-8 grade cleanroom area and specific ground support equipment.

The direct connection of the AIT center to the airport taxiway provides unique advantages in terms of safety, cost and risk management by ending the need to transport the satellite by road. Space Systems Assembly, Integration and Test Center, located at TURKISH AEROSPACE premises in Ankara, was designed to provide required services dedicated to environmental test processes to be conducted until all space systems for earth observation, communication and similar features are ready for launch activities. Besides, the facility has an infrastructure for measurements and ground testing of space systems compatible with ECSS Standards.

Within the scope of satellite “Assembly” activities, it is aimed to gather sub-systems, harness and structural parts together to form Satellite. By means of “Integration” activities, equipment and sub-system connections are performed to make Satellite functional. Assembly and Integration activities are followed by “Functional Test” activities to generate all possible scenarios related to the mission of Satellite in Space and performance verification of Satellite components.

During “Environmental Testing” process, it aimed to show endurance of satellite and components against environmental conditions during launch and mission as well as the compatibility with the customer requirements. The objective of these tests is to simulate environmental conditions encountered by satellite from launch to orbit injection as close as real conditions and to ensure that satellite and its subsystems that are exposed to these conditions are working properly.

Thermal Vacuum Tests: Satellite starts to expose to harsh space environment conditions when it reaches a certain altitude even before departing from the launcher. The simulation of low pressure (vacuum), warming up due to Sun & Earth heat fluxes and cooling down due to deep space to generate space environment is performed by Thermal Vacuum Tests.

Mass Properties Measurement: The precise measurement of mass parameters (center of gravity, moment of inertia, etc.) utilized and crucial for orbit injection of Satellite and calculation of Satellite orientation during mission is performed by Mass Properties Measurement System.

Vibration Tests: The effect of mechanical loads induced by the launcher during the lift-off on the satellite is verified by Vibration Tests. The tests are applied to main 3 axes of the satellite separately via an electro-dynamic shaker.
Acoustic Tests: The tests are performed by simulating the mechanical loads created by the powerful sound waves which are caused by the firing of the launcher by reflecting on the launcher and thus on the satellite. The satellite placed in the Acoustic Test Chamber is subjected to sound waves generated by the special horns fed by the pressurized gas nitrogen.

Shock Tests: The simulation of the shock loads occurring in stages such as separation of the launcher and separation of satellite from the launcher is carried out by pyroshock tests.

Solar Array and Antenna Deployment System: The deployment of solar panels which convert the energy from sun into electrical energy is crucial for the space mission. Therefore, prior to launch, it is necessary to verify that the solar panels will be deployed properly in space and that the shock force caused by the technical components of the pyro will not damage the satellite and solar panels.

Electromagnetic Interference/Compatibility Tests: It is aimed to be conducted in the area without reflection (isolated from RF effects coming from outside) in order to detect electromagnetic interferences that may occur while the satellite is at launch pad after being placed on the launcher and also to verify that each equipment on the satellite works in harmony with each other.

Compact Antenna Tests: Antenna tests are conducted in order to evaluate antenna performance of Satellite. By means of reflectors and feeds inside Compact Antenna Test Room, functionality and performance (antenna gain, receiver and transmitter signal power levels, etc.) of Antennas are tested via simulating the distance of Satellite in orbit from the Earth to ensure that the broadcast from Satellite is only concentrated to intended target region on the Earth.

Satellite gets ready to be transferred to launch site after successful completion of abovementioned environmental and functional tests. Please click here. for technical specifications of test systems at Space Systems Integration and Test Center where all of the mentioned tests can be performed.

In addition to national projects, Turkish Aerospace Space Systems Assembly Integration and Test Center is also planned to serve international space/satellite projects by the assistance of specialized engineers in their field and certified & trained technicians capable to work with space systems.

By means of Turkish Aerospace Space Systems Assembly Integration and Test Center that exists in few developed countries in the world, Turkey will be an international player providing assembly, integrations and test services for the space systems.
