Key Points Produces directed thrust for propulsion and attitude control Expels mass or uses force-producing mechanisms to change velocity or orientation Can be chemical or electric depending on mission needs Operates under constraints including propellant availability, thrust level, response time,…
Key Points Relays signals with minimal onboard processing Common in bent-pipe satellite designs Depends heavily on ground segment processing Supports straightforward relay architectures May amplify or shift signals but does not perform major regenerative processing Definition Transparent Payload is a…
Key Points Controls item-based production steps Often tied to machines, cells, and conveyors Common in assembly and production lines Focuses on sequencing, timing, and state transitions between units Coordinates machine steps to move each unit through production in correct order…
Key Points Keepalive Interval is the time between periodic liveness-check messages Used to detect silent failures and maintain connection state Found in routing protocols, connection management, and service monitoring Keepalive interval settings affect failure detection speed and network overhead Tradeoffs…
Key Points Provides alternate control connectivity to maintain continuity during link or device failure Reduces single points of failure in control communications Used in critical industrial control systems, process control, and safety-related systems Designed to keep control communications available if…
Key Points Control system with strict timing requirements for effective operation Depends on timely response to function correctly Used in industrial automation, robotics, safety systems, and motion control Places timing requirements on sensing, computation, and actuation Definition Real-Time Control System…
Key Points Moves service between gateway sites or paths Supports continuity and resilience Used in satellite and network operations Can be triggered by failure, coverage changes, or optimization Driven by fault recovery, coverage changes, or load balancing needs Definition Gateway…
Key Points Measures vertical pointing direction relative to a reference plane Used with azimuth for full three-dimensional orientation Common in satellite ground stations, radar, astronomy, and field alignment Depends on choice of reference plane and local terrain Often confused with…
Key Points Moves service between satellites or beams Used in constellation and mobility scenarios Supports continuity during orbital movement Requires timing and coordination Handles coverage transitions in dynamic satellite networks May include brief transition periods or signal interruptions Definition Satellite…
Key Points Requires bounded response times Used in automation and embedded systems Timing correctness is part of functional correctness Common in industrial and motion control Emphasizes deterministic timing rather than only raw processing speed Definition Real Time Control is control…
