Benefits of SAGaN for Europe’s Space Market

SAGaN (Space Application GaN transistor) is a European project whose objective is making a solid supply chain for power GaN transistors for space applications. In this blog post, we will explore what they are and the key benefits of Sagan project and its potential impact on future space missions.

Gallium Nitride (GaN) transistors are a key component for efficient electronic equipment for satellites and deep space probes. They enable electrical power management minimizing power loss during the process. This makes them particularly suitable for power electronics applications in space.

• What are GaN Transistors: Transistors are semiconductor devices that act as a switch to control the storage and release of electrical energy. GaN transistors use gallium nitride as the primary material. When compared to their Silicon counterpart, they offer superior performance in terms of speed, efficiency, and thermal management.
• Applications in Space Electronics: GaN transistors are used in various power electronics applications. In the context of space missions, they help improve the efficiency and reliability of power systems, which is crucial for the success of long-duration missions. Their use can be practical in any part of the electrical system of the spacecraft, such as primary-side regulators, current limiters, DC/DC converters, inverters or motor drivers.

GaN transistors are already available for industrial, automotive or consumer electronics, however, their use in space is scarce due to the restrictive environment that space missions experience. SAGaN project has the goal of creating new transistors that are adequate for space missions.

The SAGaN project contributes to enhance Europe’s competitive edge in the global space industry. Some of the key benefits include:

• Economic Impacts: By fostering innovation and technological advancements, the project can stimulate economic growth and attract investment in the European space sector.
• Reducing External Dependencies: The project aims to reduce Europe’s reliance on non-European countries for critical space technologies, enhancing the region’s self-sufficiency and strategic autonomy.

These benefits contribute to a more robust and dynamic space market in Europe, ensuring long-term growth and sustainability.

The technologies and innovations developed by SAGaN project have the potential to enhance future space missions. Some of the anticipated impacts include:

• Increased Potential Applications: Electrical power is very scarce in a spacecraft. This means that the design ambition of systems and instruments is constrained. As GaN transistors allow more efficient electrical systems, new applications or instruments can be considered.
• Reduction of cost. GaN transistors can be used to create smaller electronic equipment. Mass of a spacecraft is one of its costs drivers due to its impact in launch costs.
• Contributions to Scientific Research: By enabling more efficient and reliable missions, the SAGaN supports scientific research and discovery, expanding our understanding of the universe.

These contributions not only enhance mission efficiency but also open up new possibilities for exploration and discovery.

SAGaN project offers numerous benefits for the European space market and future missions. By driving technological advancements, enhancing economic impacts, and supporting scientific research, the project is set to play a crucial role in the future of space exploration.
