The nationwide availability of fast data transfer systems is a prerequisite for being able to compete in the future. By means of a global network of up to 1000 satellites, it is possible to make high-speed Internet available worldwide. The economic operation of such a satellite network depends on the provision of satellites at economically acceptable prices. Against the background of the so-called "constellations", it is becoming increasingly important to be able to produce them in higher quantities and at lower prices.
In the project "IRAS" (Integrated Research Platform for Affordable Satellites), an integrated development platform for low-cost satellites is being set up in cooperation between industry and research in Baden-Württemberg. Using new technologies of propulsion, structures, electronics and production technologies, an alternative path to today's cost-intensive development is to be taken. DLR engages in the field of structures and production technologies and pursues questions around the development and optimization of integrative construction methods for satellite structures. Researchers focus on process development for 3D printing processes for metals and ceramics as well as topology optimization and functional integration of 3D printed satellite structures.
The IRAS DCEP (Digital Concurrent Engineering Platform) shall serve as a software-based platform for the computer-aided generation of a holistic conceptual satellite design. Within IRAS, the DCEP represents the connecting element by combining the distinct expert tools and making them accessible to the end user. Thereby, it shall complement or replace the physical presence in a Concurrent Engineering Facility.
What does the future affordable satellite look like? DLR researchers try to find answers to this question in the IRAS project.
Building a numerical, integrated development platform for new technologies for low-cost satellites in collaboration between industry and research.
Developing new satellite architectures, construction methods and use of additive production processes.
