Resilience

Satcom Hardening Satcom Hardening is the strengthening of satellite communications systems against faults, interference, environmental exposure, and security threats. It improves operational resilience. Concept/Framework Satellite Communications Satellite communications is a communications architecture in which user traffic is relayed via satellites between remote endpoints and terrestrial network infrastructure. The system includes the user terminal, the space segment,… Concept/Framework Satellite Footprint Edge Satellite Footprint Edge is the outer boundary of the geographic area covered by a satellite beam or service footprint, characterized by declining signal quality and increased sensitivity to propagation conditions. Concept/Framework Satellite Operations Satellite operations is the set of activities used to command, monitor, sustain, and recover satellites during mission life. It includes scheduling, anomaly handling, station keeping, telemetry analysis, and coordination with… Operations Secure Command Channel A secure command channel is a communications channel that protects command traffic against unauthorized access, modification, and replay. It is used to deliver control instructions reliably and safely to a… Concept/Framework Sequence Control Sequence Control is control logic that executes actions in a defined order so a process or machine follows the required progression. Operations Service Assurance Service Assurance is the operational practice of monitoring, analyzing, and maintaining service performance so it meets required service levels. It links operational data to service quality through continuous measurement and… Operations Service Beam Assignment Service Beam Assignment is the assignment of a satellite beam or service region to a user, demand area, or traffic group. It links beam resources to service demand. Operations Service Chaining Service Chaining is the ordered passing of traffic through multiple network or security services before it reaches its destination. Service Model Service Continuity Service Continuity is the ability to maintain or restore a service without unacceptable interruption when conditions change or faults occur. Operations
