A new era of Earth observation is underway with the successful launch of NAHLA, a Belgian satellite designed for high-resolution environmental monitoring. The mission, known as IPERLITE, promises to deliver unprecedented daily hyperspectral imagery – data capturing a wider spectrum of light than traditional satellites – for applications ranging from climate change research to precision agriculture. developed through a collaboration between the Flemish Institute for Technological Research (VITO), the European Space agency (ESA), and other Belgian partners, NAHLA represents a critically important advancement in accessible remote sensing technology [[2]].
A new Belgian satellite, NAHLA, is now in orbit and poised to deliver high-resolution hyperspectral imaging data for environmental monitoring, agricultural analysis, climate studies, and water quality assessments. The mission, known as IPERLITE, is led by the Flemish Institute for Technological Research (VITO) in collaboration with the European Space Agency (ESA), the Belgian Federal Science Policy Office (BELSPO), and Aerospacelab.
Built on Aerospacelab’s VSP-150 platform, NAHLA integrates advanced technologies from a consortium of Belgian partners including AMOS, DELTATEC, imec, and SPACEBEL. The satellite carries CSIMBA, a hyperspectral camera capable of capturing images with a spatial resolution of 20 meters across an 80-kilometer wide swath.
Operating at an altitude of just 510 kilometers, CSIMBA collects detailed hyperspectral data using innovative techniques like digital Time Delay Integration, enabling high-quality images even with a relatively small optical aperture. This technology is crucial for maximizing data capture from smaller satellite platforms.
NAHLA is designed for rapid onboard data processing and can downlink nearly 19 GB of data daily, translating to approximately 17,500 square kilometers of hyperspectral data per day. The sheer volume of data will provide researchers and policymakers with unprecedented insights into Earth’s dynamic systems.
VITO is responsible for the calibration and validation of all satellite data, as well as data processing, quality control, and scientific assessment of performance and usability. This ensures the data’s compatibility with larger missions like PRISMA and EnMAP, facilitating broader scientific collaboration and data integration.
“We are bringing the performance of large hyperspectral missions to a smaller, more flexible satellite,” said Dr. Iskander Benhadj, Team Lead Space, Remote Sensing Systems & Technology at VITO. “The combination of advanced technology and VITO’s expertise in calibration makes that possible.”
The satellite is now entering its in-orbit testing phase. Once the instruments are fully validated, IPERLITE will begin delivering daily hyperspectral imagery, supporting more informed policy decisions and advancing scientific understanding. The mission also serves as a technological precursor for future Earth observation missions, paving the way for more sophisticated and accessible remote sensing capabilities.
