Non-Terrestrial

BVLOS Operations The operation of an uncrewed aircraft system beyond the range at which its remote pilot can maintain direct unaided visual contact, requiring a long-range command-and-control link, detection and avoidance capability,… Concept/Framework C Band C Band is a microwave frequency range used in communications systems that require robust propagation and moderate bandwidth, commonly deployed in satellite and terrestrial links. Protocol Carrier Backoff Carrier Backoff is the reduction of transmitter output level to preserve linearity or reduce interference when carrying RF carriers. Operations Carrier To Noise Ratio Carrier To Noise Ratio is the ratio of received carrier power to background noise power in a communication link. It indicates how clearly the carrier stands above noise. Concept/Framework Carrier-to-Interference Ratio Carrier-to-interference ratio is the ratio between the received carrier power and the aggregate interfering power that shares the same or adjacent channel resources. Concept/Framework 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 CNS/ATM The ICAO-defined framework integrating satellite-based communications, navigation, and surveillance technologies with automated air traffic management procedures, extending air traffic control capability into airspace beyond the reach of ground-based radar and… Concept/Framework 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 Cognitive Radio A radio system capable of autonomously sensing its RF environment and dynamically reconfiguring its own transmission parameters — frequency, power, modulation, bandwidth — in response to detected spectrum occupancy and… 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.
