Why does this matter operationally?
Resilience
The capacity of a connectivity system to maintain acceptable service levels when components fail, links degrade, or conditions change unexpectedly. Resilient architectures use redundancy, failover paths, and graceful degradation to keep operations running when ideal conditions cannot be guaranteed.

Situational Awareness
The accurate, sufficiently current understanding of a dynamic operational environment — including entity positions, prevailing conditions, and how the situation is changing — that supports effective decision-making by a person…
Concept/Framework
Smart Grid
The umbrella concept for a modernized electrical grid instrumented with two-way digital communication, sensing, and automation across generation, transmission, and distribution, providing the connectivity foundation for coordinated, data-driven grid operation.
Concept/Framework
Smart Inverter
A power electronics device converting DC power from a distributed energy resource into grid-compatible AC power, additionally providing autonomous grid-support functions — voltage regulation, frequency response, remote curtailment, and fault…
Hardware
Software As A Service
Software As A Service is a delivery model in which software is hosted by a provider and accessed over a network, removing most local software management from the user.
Service Model
Software Defined Payload
Software Defined Payload is a communications payload whose functions are controlled, configured, or reconfigured through software rather than being fixed entirely by hardware design.

Space Systems
Space systems are the collection of spacecraft, ground segments, mission control functions, and supporting infrastructure used to operate a mission in the space environment. The term includes the architecture required…
Concept/Framework
Spacecraft
A spacecraft is a hardware platform intended to operate in the space environment and perform a mission such as communications, sensing, navigation, or experimentation. It includes the structural, power, control,…

Spectrum
Spectrum is the range of electromagnetic frequencies used for communication, sensing, and other radio-related functions. It is the underlying resource for wireless systems.
Concept/Framework
Spectrum Coordination
Spectrum Coordination is the planning and management of radio spectrum use to reduce interference and allow compatible services to operate. It aligns technical and regulatory use of frequency resources.
