Satellite launch trackers consist of a combination of two optical cameras. The camera unit is protected by a CHU bracket, which is usually milled from aluminium blocks. Additive manufacturing helps to improve the design freedom and properties of the component. It cuts down on weight, volume and costs compared to conventional production. The printed component is also more rigid. By changing the material, it was possible to optimise the mechanical properties of the material on site, eliminating the need for electrochemical polishing and heat treatment. The Institute of Space Systems at the University of Stuttgart developed the CHU as part of the Flying Laptop satellite, which was developed and launched into space in 2014. It is used to accurately calculate the position and orientation of satellites in space.
