The use of remote sensing satellites for verification in international law

This paper examines the use of remote sensing satellites for verification in public international law. Verification always depends on the specific agreement or mission to be verified. There are no general framework rules: the means of verification and the verifying authorities vary from agreement to agreement and from mission to mission. Rapid technological development and the intensifying international cooperation have led to an increasing number of international verification missions. Whereas, in the past, verification was at the heart of intelligence and national services, the commercialization of the remote sensing industry and the information revolution have supported the creation of joint initiatives in this field. Traditionally, verification is associated with disarmament and arms control treaties, but the paper will underline that this is only one field of application for verification missions. It is important to note that there is no binding international regime specifically addressing such activity. The lack of legal certainty in this field also applies to the use of remotely sensed data as evidence in legal proceedings.
