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 Capacity Satellite capacity is the amount of communications demand that a satellite system can serve within its technical and operational limits. It is bounded by spectrum, power, beam allocation, modulation, and… Concept/Framework Satellite Handover Satellite Handover is the transfer of an active connection from one satellite, beam, or path to another to maintain service continuity as coverage changes. Operations SD-WAN SD-WAN is a network architecture that applies centralized policy to traffic flows across multiple wide area transport links. It typically uses branch edge devices, overlay tunnels, telemetry, and orchestration software… Service Model Secure Telecommand Channel Secure Telecommand Channel is a protected command path that ensures telecommand messages are authenticated, controlled, and resistant to unauthorized access. Protocol Secure Tunneling Secure Tunneling is the use of an encrypted or protected tunnel to carry traffic between endpoints across an untrusted network. It preserves confidentiality or integrity in transit. Protocol Segment Routing Segment Routing is a source-routing approach in which a packet carries an ordered list of instructions that guide how the network forwards it. It encodes path behavior in segments. Protocol Service Handoff Service handoff is the operational process of moving an ongoing connection, session, or service flow from one network element or path to another while preserving continuity as much as possible.… Concept/Framework Signal Masking Signal Masking is the use of spectral, timing, or power behavior that makes a signal harder to detect, identify, or isolate. It lowers signal observability. Operations Signal Strength Signal strength is the measured level of received radio energy at a receiving point. It is a basic indicator of link quality and propagation conditions. Concept/Framework
