TU Delft's Alticube+ Selected for ESA's Water Level Monitoring Mission
Delft, Thursday, 4 July 2024.
The European Space Agency has chosen TU Delft’s Alticube+ concept for global water level monitoring. This innovative system uses multiple small satellites with long deployable arms to create detailed 3D imaging, potentially revolutionizing water resource management and warning systems worldwide.
Innovative Radar Technology
Alticube+ is an advanced radar altimeter designed by TU Delft, based in Delft, Netherlands. This system leverages radar interferometry to obtain highly accurate measurements of water levels in various environments, including coastal areas, rivers, and lakes. The technology’s promise lies in its ability to deliver more frequent, precise, and cost-effective data compared to traditional methods, which often involve complex and expensive systems.
The Concept of CubeSat Swarms
At the heart of Alticube+ is the use of CubeSats—small, compact satellites that work in swarms. These CubeSats are connected by long deployable arms, creating a baseline of ten meters or more. This configuration allows the satellites to perform detailed 3D imaging, which is crucial for monitoring water levels accurately. The use of small spacecraft working in unison marks a significant shift from the traditional approach of using a single, larger satellite.
Collaborative Efforts and Development
The development of Alticube+ is a collaborative effort involving TU Delft, COMET Ingeniería, and ISISPACE. These organizations have combined their expertise to create a miniaturized radar altimeter that can be deployed on CubeSats. The Radar Instruments and Applications knowledge network has provided essential support, helping to overcome the challenges of designing suitable instruments for such small platforms. Professor Peter Hoogeboom from TU Delft highlighted the importance of this support in advancing the project.
Potential Impact on Water Resource Management
Alticube+ aims to revolutionize the way water levels are monitored globally. By providing more accurate and frequent data, it can enhance early warning systems for floods and droughts, aiding in disaster preparedness and response. Furthermore, the long-term data collected by Alticube+ will contribute to a better understanding of global water systems, influencing policy decisions and resource management strategies. This innovation aligns with the European Space Agency’s vision of using space technology to address critical environmental challenges.
Recognition and Future Prospects
The selection of Alticube+ by the European Space Agency is a testament to its potential impact. TU Delft and its partners presented their findings in April 2024, showcasing the system’s capabilities. The ESA sees the use of swarms of small spacecraft as a revolutionary step in space technology, with Alticube+ being one of the seven proposals chosen for further development. This recognition highlights the project’s promise and sets the stage for its future deployment and operationalization.
