The special product requirements
During the development of TÜRKSAT 6A, Turkish Aerospace prescribed a weight reduction for the structure of the geostationary satellite and subjected each individual structural part to appropriate optimization. One of these structural elements is the bracket for an optical measuring device known as the "star tracker", which continuously records the satellite's position in relation to the constellation of stars to determine its exact position in orbit.
Turkish Aerospace's goal for the Star Tracker bracket was to
At the same time, the new bracket had to be competitive from a cost perspective compared to the conventionally manufactured mount used to date.
Based on these requirements, FIT design experts developed a completely new design as part of an ADM-E project and optimized it until it met all component requirements.
The bracket was manufactured in aluminum (AlSi10Mg) using laser melting (PBF-LB/M), then blasted, milled on the functional surfaces, and underwent a final extensive quality control. We call this solution ADM-Q or qualified single-part manufacturing.

By re-engineering the design and additive manufacturing the bracket, Turkish Aerospace has benefited from the following results:
In addition, the complexity of the bracket was significantly reduced, as it is no longer manufactured from many individual parts, but in one piece. This has resulted in further advantages:
Under these circumstances, the cost of the additively manufactured bracket was significantly lower than that of the conventionally manufactured mount.
Turkish Aerospace found with FIT all the services from a single source that were required to develop a lightweight component from a complex and heavy structural element that meets the high demands of space travel. Mission accomplished!
