Earth Segment Earth Segment is the ground-based part of a satellite communications system that includes infrastructure supporting control, telemetry, tracking, and service access from Earth. Hardware Electromagnetic Spectrum Operations The formal military doctrine integrating electronic warfare, spectrum management, and signals intelligence into a single coordinated operational discipline, treating the electromagnetic spectrum as a contested operational domain requiring deliberate cross-functional… Concept/Framework Electronic Warfare The military discipline of using the electromagnetic spectrum to degrade, deny, or deceive an adversary's electronic systems, encompassing attack techniques such as jamming and GNSS denial alongside protective measures defending… Concept/Framework Emergency Connectivity Emergency Connectivity is connectivity designed to remain available or rapidly restore communication during emergencies. It supports continuity when normal service is disrupted. Operations Emission Control Emission Control is the management of signal emission level, direction, timing, or pattern to reduce detectability or interference. Operations Encrypted Payload Traffic Encrypted Payload Traffic is payload data that is protected by encryption as it moves across a satellite or communications network. Software Field Communications Field Communications is the communications environment and practice used by personnel operating away from fixed infrastructure to support deployed communications in the field. Operations Frequency Hopping Frequency Hopping is the periodic change of carrier frequency according to a predefined or adaptive sequence. Protocol GNSS Denial The operational condition in which a device or region loses access to reliable GNSS positioning and timing, typically caused by jamming or spoofing directed at GNSS signals, affecting every downstream… Concept/Framework Hardened Terminal Hardened Terminal is a communications terminal designed to resist environmental stress, damage, interference, or operational disruption while maintaining functional communications capability in demanding field conditions.
