Ground Segment

Antenna Blockage Superstructure Antenna Blockage Superstructure is a vessel structure that obstructs an antenna's line of sight and reduces or interrupts radio performance through physical blockage or partial shadowing of the RF path. Hardware Azimuth Azimuth is the horizontal reference used to describe direction or bearing relative to a chosen origin, commonly measured from north in navigation and pointing tasks. Concept/Framework Azimuth Angle Azimuth Angle is the horizontal angular direction of an object or target relative to a chosen reference, commonly north. It is used to describe orientation in a horizontal plane. Concept/Framework Deck Mounted Antenna System Deck Mounted Antenna System is a shipboard antenna installation placed on the vessel deck or superstructure to provide communications coverage at sea while accounting for motion, blockage, salt exposure, and… Hardware Deployable Ground Station Deployable Ground Station is a ground station that can be transported and set up at a new location to provide temporary or flexible communications support. Hardware Digital Payload Digital Payload is the data-bearing part of a communications payload that handles user traffic or service information. Software Earth Segment Earth Segment is the ground-based part of a satellite communications system that includes infrastructure supporting control, telemetry, tracking, and service access from Earth. Hardware Earth Station Earth Station is a ground-based satellite communications facility that transmits and receives signals to and from spacecraft. It provides the terrestrial side of the satellite link. Hardware Elevation Angle Elevation Angle is the vertical angle between a horizontal reference plane and a target direction. Concept/Framework Ephemeris Ephemeris is the set of time-based position data used to determine the location of a satellite or celestial object. It supports tracking and navigation. Operations
