GHGSat-D, also known as Claire, is a 15-kilogram microsatellite built by the University of Toronto’s Space Flight Laboratory with two spectrometers developed and manufactured by MPB Communications.
GHGSat-D, GHGSat-C1, GHGSat-C2, and the next three GHGSat smallsats were or will be developed on SFL’s 15-kilogram Next-generation Earth Monitoring and Observation (NEMO) smallsat platform.
GHGSat Inc. awarded SFL the development contracts for GHGSat-C1 ("Iris") and GHGSat-C2 ("Hugo") after SFL built and launched the pathfinding GHGSat-D ("Claire") atmospheric monitoring smallsat in 2016.
GHGSat first selected SFL in 2013 to develop the GHGSat-D demonstration satellite known as Claire to prove on-orbit stability and sensor pointing on a small satellite platform.
