Pointing Mirror for Wide-Angle Fabry-Pérot Spectrometer — The project will evaluate the advantages of a pointing mirror as a technology candidate for reducing the detection threshold and increasing the coverage and capacity of GHGSat’s wide-angle Fabry-Pérot (WAF-P) spectrometer. The project will build on heritage technology from GHGSat, and its partners with lessons learned from a predecessor project supported by the Science and Technology Development Program (STDP) as well as updated simulations and operational experience from GHGSat’s existing satellite constellation. This project will advance technologies required for GHGSat’s next generation spectrometer sensor to achieve significantly reduced greenhouse gas detection thresholds while increasing coverage and measurement capacity. If successful, GHGSat intends to fly the next generation spectrometer sensor as an experimental hosted payload on a third-party satellite, followed by large-scale deployment in a constellation. Support for this project will accelerate GHGSat’s efforts to monitor
