Why does this matter operationally?
Performance
The measurable behaviour of a connectivity system under real operating conditions, including throughput, latency, jitter, and packet loss. Performance determines whether applications and control systems receive data at the speed and consistency their operations require.

SIP
A signaling protocol used to establish, modify, and terminate real-time communication sessions such as voice and video calls, handling session setup and control while a separate transport protocol carries the…
Protocol
Site Diversity
Site diversity is the deployment of equivalent or complementary functions across separate sites so service can continue when one location is impaired.
Concept/Framework
Soft Real-Time Constraint
Soft Real-Time Constraint is a timing requirement that should usually be met, but occasional misses reduce quality rather than causing immediate failure.
Operations
Software Defined Networking
Software Defined Networking is a network architecture that separates control logic from forwarding behavior and manages the network through software-based control. It decouples decision-making from packet handling.
Concept/Framework
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.
Hardware
Solid-State Power Amplifier
Solid-State Power Amplifier is a power amplifier that uses semiconductor devices rather than vacuum tubes to increase RF output power.
Hardware
Space Segment
Space Segment is the portion of a satellite system located in space, including spacecraft, payloads, and orbiting assets that provide the service.
Hardware
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…

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,…
