The NASA-ISRO Synthetic Aperture Radar (NISAR) mission, launched in July 2025, is the first dual-frequency radar satellite, enhancing Earth observation. It maps land and ice every 12 days, aiding in environmental monitoring, natural hazard assessment, agriculture, and cryosphere research. NISAR promotes open access to radar data, fostering innovation globally.
The 2025 CVPR paper “Gaussian Splatting for Efficient Satellite Image Photogrammetry” introduces a new 3D representation method using Gaussian primitives, improving processing efficiency for satellite imagery. This approach promises faster reconstruction with reduced computational costs while maintaining accuracy, benefiting geospatial professionals through enhanced operational efficiency and scalability in mapping applications.
The European Space Agency’s Biomass satellite, launched in April 2025, will revolutionise forest management by employing P-band radar technology to measure woody biomass accurately beneath dense canopies. This innovation aids in carbon stock assessments, enhances climate monitoring, and supports global conservation efforts and regulatory frameworks for carbon accounting.
