SFL Missions Awarded Contract for Additional GHGSat Greenhouse Gas Monitoring Microsatellites

  • Rating12345

SFL Missions has been awarded a contract by GHGSat of Montreal to develop two additional commercial microsatellites for the GHGSat greenhouse gas monitoring constellation.

GHGSat-C18 and -C19 are being built, integrated, and tested at the SFL Missions facility in Toronto where 37 satellites are currently under development for commercial, government, and research organizations worldwide.

SFL Missions is developing GHGSat-C18 and -C19 on the same low-cost, high-performance 15-kg NEMO platform used to build 11 GHGSat satellites over the past decade. Once completed, the satellites will be transported to Vandenberg Space Force Base in California for launch together on a SpaceX Transporter mission.

“SFL Missions is pleased that GHGSat continues to rely on our exceptional record of on-orbit success and space-proven microspace technology as the foundation for its industry-leading greenhouse gas monitoring constellation,” said SFL Missions Director and CEO Dr. Robert E. Zee. “Our smaller satellite platforms offer a combination of size, performance, and cost effectiveness that is unmatched in the aerospace sector today.”
