Key Points Provides alternate paths or components Used to increase availability and fault tolerance Appears in networks, control systems, and infrastructure Can be active-active or active-standby Requires deliberate design at correct failure domain Common failure modes include split-brain conditions, failed…
Key Points Coding Rate is the ratio of payload bits to total encoded bits Indicates the proportion of transmission devoted to redundancy Used across network and system environments Balances robustness against usable throughput Critical design parameter in error-control systems Definition…
Key Points Executes onboard software and control logic Interfaces with sensors and actuators Supports autonomy and command execution Processes sensor data and issues control actions Manages timing and sequencing of subsystem behavior Operates independently or safely when communication is limited…
Key Points Maintains antenna pointing across three rotational axes (roll, pitch, yaw) Uses active stabilization control with motors or actuators Senses platform motion and compensates in real time Supports stable satellite tracking on moving platforms Critical for narrow-beam communications requiring…
Key Points Phase Alignment is the adjustment of phase relationship between signals or clocks Used across network and system environments to support coherent transmission Critical in radio systems, clocks, signal processing, and industrial synchronization Requires measurement of relative phase difference…
Key Points Manages how spectrum is shared or assigned Used in satellite and terrestrial environments Helps reduce interference and conflicts Involves technical and regulatory constraints Combines spectrum engineering with regulatory and operational planning Considers frequency assignments, power levels, geography, and…
Key Points Supports recovery from major outages Uses cloud-hosted backup or standby resources Common in continuity planning Can reduce recovery time and infrastructure duplication Often includes standby systems, replicated data, and tested failover procedures Requires recovery time objectives and recovery…
Key Points Portable or rapidly deployable Supports temporary coverage or mission needs Used for recovery, events, and remote operations Packages ground station functions into relocatable systems Deployed where needed, then connected to required network or mission service Definition Deployable Ground…
Key Points Measures link uptime or service readiness over time Used in radio, satellite, microwave, and transport planning Shaped by weather, interference, equipment behavior, and redundancy design Depends on impairments and redundancy architecture Often expressed as a percentage Incorporates rain…
