Chemical Propulsion Chemical Propulsion is a propulsion method that generates thrust by releasing energy from a chemical reaction. It converts stored reactants into directed exhaust. Hardware Co Channel Interference Co Channel Interference is interference that occurs when two or more transmitters use the same frequency channel in overlapping coverage areas. It degrades reception quality and capacity. Concept/Framework Command and Data Handling Command and Data Handling is the spacecraft or remote-system function that routes commands, collects data, and manages onboard data flow. Software 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 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 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
