Military Satellite Communications

Military satellite communications refers to the use of satellite systems to provide secure, reliable communications for military and defense users, supporting command and control, intelligence dissemination, situational awareness, logistics, and tactical operations. These systems are designed to operate in contested and degraded environments and typically emphasise availability, survivability, and security over raw data throughput.

Military satellite communications may employ dedicated military satellites or make use of commercial and dual-use systems. Capabilities commonly include protected waveforms, encryption, access control, and resilience measures such as spread spectrum, frequency hopping, adaptive power control, and anti-jam techniques. Services range from narrowband voice and messaging to broadband data, imagery, and video distribution.

Military satellite communications systems operate across a wide range of frequency bands, including UHF, L-band, X-band, Ka-band, and EHF, with different bands selected to balance coverage, capacity, resistance to interference, and terminal size.
