Digital Payload Digital Payload is the data-bearing part of a communications payload that handles user traffic or service information. Software Doppler Compensation Doppler Compensation is the adjustment of frequency or timing to counteract Doppler shift caused by relative motion between transmitter and receiver. Operations Downlink Downlink is the communication path from a transmitter or network toward a receiver or end user device. It is the receive direction in a bidirectional link. Protocol Drone Command Link Drone Command Link is the control link used to send commands to a drone or unmanned aerial vehicle and receive operational feedback, enabling remote drone operation and situational awareness. Hardware Horizon Masking Horizon Masking is the obstruction or loss of visibility near the horizon caused by the Earth, terrain, or vessel geometry. It blocks low-angle paths and prevents RF signals from reaching… Concept/Framework In-Flight Connectivity In-flight connectivity is the service model that provides internet or network access to passengers and crew on board an aircraft while it is in flight. It uses airborne and external… Service Model Interference Margin Interference Margin is the headroom a communication link has before interference degrades service below acceptable levels. It is a planning measure used to assess resilience. Operations Ka Band Ka Band is a microwave frequency range used in high-capacity communication systems, commonly employed in satellite and fixed wireless links to support wider bandwidth and higher data throughput. Hardware Ku Band Ku Band is a microwave frequency range used in satellite and broadcast communications that supports directional links at frequencies sensitive to weather effects. Concept/Framework L Band L Band is a lower microwave frequency range used in communications and navigation systems, valued for propagation characteristics and broad service support. Hardware
