The Göktürk-1 programme is focused on the construction by Telespazio and Thales Alenia Space, for the Turkish Ministry of Defence, of a satellite for Earth observation with a high-resolution optical sensor, a satellite integration and test centre in Turkey, and the complete ground segment, which will be in charge of mission control, in-orbit operation, data acquisition and processing. Local industrial partners include TAI, Aselsan, TÜBITAK UEKAE, Roketsan and TR Teknoloji.
The Turkish industry has been involved in the system design and development, as well as in the supply of certain Göktürk-1 system components: TAI provided elements of the satellite payload structure, Aselsan is in charge of the ground segment’s data acquisition and processing, TÜBITAK UEKAE is in charge of remote control and telemetry ciphering devices and TR Teknoloji is responsible for the AIT Centre building.
The satellite launch is foreseen in 2016.
Telespazio is the prime contractor and system integrator and, in addition, is building the entire ground segment for the system to carry out in-orbit operation and data acquisition and processing. Telespazio is also responsible for the satellite launch, early orbit and test services. For the development and marketing of Göktürk-1’s data and application services the establishment of a joint venture with local partners is foreseen.
Thales Alenia Space
Thales Alenia Space has built the satellite and has developed the integration and test centre in Turkey, an infrastructure designed to simultaneously integrate different satellites. Derived from the Proteus platform developed by Thales Alenia Space, the Göktürk-1 satellite includes a high-resolution optical instrument, which is the result of the company's strong experience in this field.
The Göktürk-1 satellite has a dry weight of about 1,000 kg and a design life of seven years. Its observation payload includes an onboard X-band digital imaging system to handle data compression, storage, and downloading. From its sun-synchronous orbit at an altitude lower than 700 km, the satellite’s revisit time over Turkey will be less than two days.
Thales Alenia Space, in the frame of the Gokturk-1 contract with Telespazio, will be the first company in the space industry to deliver a turnkey integration and test centre. The Class 100,000 clean rooms, spanning more than 3,000 square metres, will house all the latest-generation equipment needed for satellite integration and testing. The systems include a test for mechanical vibrations (shaker), an acoustics testing room of 950 cubic meters, a thermal vacuum chamber of 350 cubic meters, a testing ground for compact antennas and support for the deployment of solar panels and antennas. Other resources include a system for testing the physical properties of the satellites (weight, centre of gravity, inertia) and verification systems for electromagnetic compatibility (EMC).
Airborne & Space Systems Division
The Airborne & Space Systems Division provides the SIREUS sensor, a micro-electromechanical technology (MEMS) gyroscope, which serves for the initial determination of the satellite position.
