Communications Payload Communications Payload is the payload portion of a spacecraft or platform that performs the communications mission. It handles the useful communications function of the asset. Hardware Contested Environment Communications Contested Environment Communications is communications designed to continue operating when interference, jamming, or adversarial conditions are present. Concept/Framework Coverage Extension Coverage extension is the deliberate increase of a network’s service area through new infrastructure, new beams, relays, or redesigned access topology. Concept/Framework Coverage Footprint Coverage Footprint is the geographic area in which a service, signal, or network resource provides usable coverage. It describes the service reach on the map. Concept/Framework Coverage Planning Coverage planning is the engineering process of estimating service availability and quality across space, terrain, or operational zones. It combines link budget, propagation, and infrastructure placement decisions to define where… Concept/Framework Cross-Strapping Cross-Strapping is the interconnection of redundant components so that one unit can be routed to alternate paths or loads when needed, supporting flexible failover. Hardware Crosslink Routing Crosslink Routing is the routing of traffic between peers or nodes that connect directly to each other rather than through a central hub, using direct inter-node paths. Protocol Datalink Communications The category of digital, text-based communication systems exchanging messages, clearances, and operational data between aircraft and ground systems — air traffic control and airline operations — as an alternative or… Concept/Framework Differential GNSS A correction technique that improves GNSS positioning accuracy by comparing a fixed reference station's known, surveyed position against its GNSS-derived position, then broadcasting the resulting correction to nearby receivers to… Concept/Framework Direct To Cell Direct To Cell is a service model that connects mobile devices to cellular services using satellite-enabled access. It extends coverage where terrestrial access is limited or unavailable. Service Model
