Last week, Rayference participated in the European Space Agency - ESA DigitalTwinEarth Components: Open Science Meeting 2026 in ESRIN - alongside the DTE S2GOS (https://dte-s2gos.rayference.eu/) mid-term review meeting, an important milestone to reflect on progress, alignment, and next steps within the project.
The SATRISE journey started back in November 2025!
SATRISE is an European Space Agency - ESA-funded innovation project that brings together advanced Earth Observation satellite data and state-of-the-art 3D simulation to redefine how solar irradiance is estimated for photovoltaic (PV) systems. By combining Rayference’s CISAR algorithm with LuciSun’s GPU-based 3D modelling tool, LuSim, SATRISE aims to deliver unprecedented accuracy in solar resource assessment for complex PV applications such as bifacial PV, agrivoltaics, urban PV, and building-integrated photovoltaics (BIPV).
The Eradiate Workshop 2025 will take place at ESA’s European Space Research Institute (ESRIN), in Frascati (Italy) on 16–17th November 2025. It will be organized jointly with ESA’s Sentinel-2 Validation Team Meeting, held on 13th-15th October 2025. Registration is open, and a dedicated page introduces the scope of the workshop, deadlines and registration procedure. More information on the Eradiate’s website.
In this study, we test the ability of the Eradiate RTM to simulate the reflectance of a manufactured target given SItraceable measurements of its shape and optical properties.
We’re excited to share our latest work: “Elaboration of Simulated Calibration Reference over Pseudo-Invariant Calibration Sites (PICS)” — now published in Atmosphere MDPI. This work has been funded through the European Space Agency - ESA’s HyperPICS (QA4EO) and EUMETSAT’s RPV4PICS projects.
