GHGSat has ordered another four 16U cubesats from Spire Global for a launch no earlier than 2024 to expand its greenhouse gas-monitoring constellation, the Canadian satellite operator announced Aug. 8.
The satellites, each the size of 16 cubesats, are identical to the three GHGSat ordered from Spire last year for a launch in late 2023.
GHGSat currently has nine satellites in low Earth orbit, built by the University of Toronto’s Space Flight Laboratory (SFL) and are about the same size.
The seven additional satellites from Spire will increase the frequency of the constellation’s observations and coverage as part of plans to monitor emissions daily from every industrial source, GHGSat said without elaborating.
