ABSOLUT SENSING

Reducing global warming is the key challenge we must face in the next years. Methane (CH4) accounts for a third of temperature increase resulting from greenhouse emissions. Countries worldwide have collectively signed the Global Methane Pledge to decrease CH4 emissions by 30% by 2030. However, to date, existing data are both too expensive and not accurate enough to allow precise quantification and regulation of CH4 emissions. Absolut Sensing is building GESat, a satellite constellation to provide regulators and companies with accurate and affordable CH4 data. We achieve this thanks to ground-breaking innovations: a compact optical system, a miniaturized cryogenic spectro-imager and an AI-amplified data processing chain. Our constellation will reach a better detection threshold (>30kg/hour/CH4), revisit rate (daily measurement across all high methane emitting areas worldwide), and quantification precision (>95% regardless of weather conditions) at a better cost (<2€/km2).
