Abstract
GEI-SAT constellation will embark SATLANTIS’ solution for methane emissions detection and quantification. GEI-SAT pursues hot spot mapping of low emission levels of methane with a low-mass and low-cost very high-resolution multispectral SWIR camera onboard CubeSats & Microsats. The overall mission consists of: GEI-SAT Precursor, a 16U CubeSat (17.4 kg, ~150 kg/h detection threshold, 1.65 m resolution @VNIR and 13 m resolution @SWIR, up to 1700 nm) to be launched in Q1 2023; GEI-SAT Plus, a Microsat (92 kg, ~100 kg/h detection threshold, 0.8 m resolution @VNIR and ~7 m resolution @SWIR, up to 1700 nm) to be launched in Q4 2023; and another three Microsats with better detection threshold (92 kg, ~50 kg/h (TBC) detection threshold, 0.8 m resolution @VNIR and 9m resolution @SWIR, up to 2300 nm) to be launched in 2024-25. The Ground Segment will include the Mission Operations & Control Centre, the Ground Stations Network and the Data HUB. The methane absorption is obtained measuring the differential signal between SWIR images with different filters. The high spatial resolution that GEI-SAT provides in its SWIR channel, together with the geo-localization provided by very high resolution VNIR channel, will allow users to distinguish the exact location of methane emissions.
