What is dual-use in the satellite context?
Dual-use in space refers to satellite systems, technologies, and services that can serve both civilian commercial applications and government, military, or national security requirements. The concept is foundational to the modern space industry: GPS was developed by the US military but enables a $100+ billion civilian navigation and location-based services economy. Copernicus is funded as a civil EU programme but its data is extensively used by European defence and border security agencies.
Commercial satellite operators and government business
Major commercial satellite operators (Intelsat, SES, Viasat, Eutelsat, Inmarsat) generate significant revenue from government and military customers who lease commercial bandwidth for tactical communications, intelligence gathering support, and mobility applications. MILSATCOM (Military Satellite Communications) uses dedicated military satellite systems for the most sensitive applications but relies extensively on commercial COMSATCOM (Commercial SATCOM) for the majority of deployed bandwidth requirements. The US Department of Defense is one of the largest buyers of commercial satellite bandwidth globally.
Starlink and the Ukraine precedent
The deployment of SpaceX Starlink terminals in Ukraine from 2022 for both civilian communications and military operations demonstrated the dual-use reality of LEO mega-constellations at scale. The same terminals used for crew welfare on merchant ships were used for drone coordination and military communications. This blurring of civil and military use raises complex questions about the legal status of commercial space infrastructure in conflict under international humanitarian law.
Export controls
Dual-use space technology is subject to strict export control regimes: the US ITAR (International Traffic in Arms Regulations) and EAR (Export Administration Regulations) regulate the export of satellite hardware, software, and technical data with potential military application. European dual-use regulations (EU Regulation 2021/821) impose similar controls. Navigating these regulations is a significant operational challenge for international satellite manufacturing and service provider businesses.
