Introduction
This project consists of the fabrication of a Sentinel-1 satellite mockup at a 1:4 scale, with an approximate diameter of 5 meters, designed for suspended exhibition. The piece has been developed as an educational and representative element for the academic and scientific environment of TU Wien, specifically for the geo-information area associated with geo.tuwien.ac.at.
The main objective of the model is to bring Earth observation space technology closer to the public, facilitating the understanding of the architecture, dimensions, and mission of the original satellite through a physical representation with strong visual impact.
Description of the mockup
The mockup reproduces the general geometry of the Sentinel-1 satellite, maintaining reduced proportions while remaining faithful to its real structure. With a diameter of 5 meters, the model is designed to be suspended in indoor or semi-outdoor spaces, allowing immersive viewing from different angles.
Main features:
- Scale: 1:4 relative to the real satellite
- Total diameter: ~5 meters
- Structural design optimized for suspension
- Visual representation of solar panels and main body
- Lightweight materials for safe overhead installation
- Educational and exhibition-oriented approach
This type of installation transforms a low Earth orbit satellite into a tangible object, facilitating its interpretation in educational, museum, and scientific outreach contexts.

European Space Agency (ESA)
The European Space Agency is the intergovernmental organization responsible for coordinating space exploration in Europe. Its work covers the development of scientific missions, Earth observation, solar system exploration, and advanced space technologies.
ESA collaborates with multiple European institutions, companies, and research centers, promoting open access to satellite data and fostering innovation in applications such as climatology, mapping, natural disaster management, and environmental monitoring.
Within its Earth observation program, the Sentinel satellite family stands out, developed under the European Union’s Copernicus program.
Sentinel-1 Satellite
Sentinel-1 is an Earth observation mission based on synthetic aperture radar (SAR) technology. It is part of the Copernicus program and is designed to provide images independent of weather conditions and sunlight.
Main functions:
- Monitoring land and sea surfaces
- Detecting changes in terrain (floods, landslides, deforestation)
- Observing polar ice and glaciers
- Supporting emergency and disaster management
- Monitoring oceans and maritime traffic
Key technical features:
- SAR radar technology (operates day and night)
- High global revisit frequency
- Systematic coverage of large areas
- Open data for the scientific community and industrial applications
Thanks to these capabilities, Sentinel-1 has become a key tool for continuous Earth analysis and decision-making in environmental and security contexts.
Conclusion
The Sentinel-1 satellite mockup at a 1:4 scale is not only an engineering and design exercise, but also a high-impact scientific outreach tool. Its installation allows the tangible visualization of the scale of modern space systems and strengthens the connection between academic research and real space missions developed by ESA.
These types of projects help bring space technology closer to the public, fostering understanding of the crucial role satellites play in observing and protecting our planet.
