Satellite audio frequency jamming: legal and regulatory challenges
1. Applicable international legal frameworks
Outer Space Treaty (1967) prohibits harmful interference with other states’ space activities and requires “due regard” for their interests .
International Telecommunications Union (ITU) Radio Regulations explicitly ban “harmful interference” in satellite communications and obligate states to prevent it, although enforcement remains weak ().
2. State responsibility and attribution
Under customary international law, a state is responsible for transboundary harm caused by its territory or agents. Jamming—whether accidental or deliberate—can trigger wrongful-state liability .
Identifying the origin of jamming (civilian, military, non-state actors) is legally and technically challenging, complicating attribution and invocation of remedies.
3. Use of force and electronic warfare
ITU law treats jamming as a spectrum violation, separate from the law of armed conflict. Yet, under the UN Charter Article 2(4), severe or militarized jamming may be characterized as a “use of force,” but threshold definitions remain unclear.
Debating whether jamming is a weapon involves assessing its non-lethal yet disruptive nature—a subject explored by Schendzielos (2007) in relation to space-based electromagnetic jamming systems .
4. Regulatory gaps and enforcement
ITU regulation prohibits interference but lacks robust state-to-state enforcement mechanisms. There is no dedicated court or tribunal for spectrum violations in space .
COPUOS and UN bodies have repeatedly called for stronger international norms, but binding agreements on jamming remain elusive .
