Performance

GEO GEO is geostationary Earth orbit, an orbital regime where a satellite remains approximately fixed relative to a point on Earth. It supports persistent coverage of a region through orbital mechanics… Concept/Framework Graceful Degradation Graceful Degradation is the controlled reduction of system capability so a service continues operating in a limited or simplified form during stress or failure. It preserves partial function. Operations GRE Tunnel GRE Tunnel is a generic routing encapsulation tunnel that carries one network protocol inside another across an intermediate network by wrapping payload protocol in a GRE header. Protocol Gyro-Stabilized Antenna Gyro-Stabilized Antenna is an antenna system that uses gyroscopic sensing or stabilization control to maintain pointing on a moving platform. It compensates for motion and disturbance. Hardware Handoff Management Handoff Management is the control and coordination of transferring active sessions or connections between access points, cells, beams, or other serving nodes while minimizing interruption. Operations Handover Handover is the transfer of an active connection or service session from one node, cell, beam, or coverage area to another. It supports continuity during movement or reallocation. Operations Hard Real-Time Constraint Hard Real-Time Constraint is a timing requirement that must be met every time because missing the deadline causes system failure or unsafe behavior. Operations High Throughput Satellite High Throughput Satellite is a satellite system designed to deliver higher data capacity than traditional satellite systems, usually by using spot beams and frequency reuse to focus resources into smaller… Hardware High-Gain Antenna High-Gain Antenna is an antenna that concentrates energy in a narrow beam to increase effective signal strength in the desired direction by shaping the radiation pattern to focus transmitted or… Hardware Holddown Timer Holddown Timer is a routing control mechanism that temporarily suppresses acceptance of route changes after a failure to reduce routing instability by holding a route in a suppressed state for… Operations
