Recently German Orbital Systems received the request from Airbus Safran Launchers to organize the workshop on New Space approach to space system development, showing which things New and Old Space have in common while emphasizing the differences.
As a result, the workshop was conducted from May 15th to May 19th at Sindringen & Forchtenberg consisting of a series of theoretical and practical sessions aimed at giving insight about small satellite missions.
Airbus Safran Launchers was represented by people from several locations from France and Germany with different backgrounds: from launch vehicles over to satellite components, from manufacturing to marketing and innovation.
The focus of the workshop was the design process of a typical CubeSat. During four days of the workshop, CubeSat-specific aspects of different engineering domains were addressed and practical exercises were carried out.
The theoretical part started with the market overview and the place of Newspace companies such as German Orbital Systems and ECM Space Technologies in the space industry value chain. After that, the history of the CubeSat missions was covered and the most interesting missions were discussed. The participants also focused on different launch opportunities for small satellites and requirements for the CubeSat design. Later each of the CubeSat’s subsystems design process was investigated starting with the structure and finishing with attitude determination and control system.
The practical sessions focused on hands-on exercises. Different systems, such as OBC and EPS as well as a communication module and a sun sensor have been tested and programmed in three groups. A flat satellite adapter has been used for effective and smooth work. The work was carried out with real satellite hardware and provided the best possible insight to CubeSat design process. During the final practical session, the subsystems have been integrated into a structure and formed a fully functional CubeSat, which was later integrated into an ECM CubeSat dispenser system. After separation, the satellite was able to work and to send telemetry, such as the sun vector via UHF after separation. A D-Star repeater and beacon also have been used during practical sessions. At the end, the participants were able to assess the effort needed to build a CubeSat from COTS (commercial off-the-shelf) subsystems.
“Four-day event passed by very fast due to great Airbus Safran Launchers team involvement and interest to new disruptive approaches to space systems design. It was really great to work with such talented and smart people and we are looking forward to future cooperation with Ariane Group,” – said Walter Ballheimer, CEO of German Orbital Systems.
