In many conflicts, international ceasefire monitors are deployed to mitigate future violence. Increasingly, such monitors use satellite imagery, uncrewed aerial vehicles, and other camera-equipped assets to supplement, and sometimes substitute, human monitoring efforts to document ceasefire violations. To date, we know little about when and how such technology contributes to ceasefire compliance, with scholars offering diverging assessments of the effects. Integrating scholarship on the use of remote sensing in ceasefire monitoring with theories on the causal processes underlying ceasefire monitoring, this analytical essay offers a framework to assess the contribution of remote sensing to ceasefire compliance and illustrates the empirical application of this framework by examining the most technologically advanced ceasefire monitoring mission yet deployed, the Special Monitoring Mission in Ukraine. Focusing on the period prior to the Russian invasion of 2022, our research finds that while the mission’s observational power was expanded, remote sensing technologies ultimately had little effect on modifying conflict party behavior or compliance. While in this case remote sensing technology minimally increased compliance, the study contributes to debates on the use of technology as a conflict management tool, and provides an assessment framework for scholars and for policymakers considering adopting technology in other monitoring contexts.
