In March 2023, the United Nations Institute of Disarmament Research (UNIDIR) conducted a field experiment, simulating an on-site inspection to verify the absence of nuclear warheads at a military site. As part of the experiment, UNIDIR, in collaboration with Open Nuclear Network (ONN), tested the applicability of commercially available satellite imagery to support the inspection.
