December 8, 2021 – GHGSat, the world leader in high-resolution remote sensing of greenhouse gas emissions, is building on its momentum to deploy a constellation of satellites in collaboration with the global technology leader ABB. GHGSat’s next three satellites, GHGSat-C3, C4 and C5, will be launched into orbit in summer 2022 on a SpaceX Falcon 9 rocket as part of the Transporter-5 mission. GHGSat also announced that it has exercised a contract option with ABB to provide six more payloads for monitoring methane emissions as well as a payload to detect CO2 emissions. The payload for Luca has been transferred to the Space Flight Laboratory (SFL), the satellite provider and integrator. Payload integration is now complete, and all tests have been finalised. The payloads for Penny and Diako will be dleivered to SFL in the coming weeks to undergo the same process later this December. The new satellites are based on the same design as GHGSat-C1 (Iris) and GHGSat-C2 (Hugo). However, several specific improvements are included to enhance data processing and communication capacity.
