Payload The mission-functional equipment a satellite carries specifically to perform its communications, sensing, or scientific mission, distinct from the satellite bus, which provides the underlying power, propulsion, and structural support the… Hardware Payload Module Payload Module is the portion of a communications system that carries the mission or service payload rather than the supporting platform functions. It contains the useful function of the system. Hardware Payload Scheduling Payload Scheduling is the planning and sequencing of payload activity, resource use, or service windows over time. It controls when payload functions run. Operations Phase Noise Phase noise is the undesirable short-term fluctuation of a signal’s phase around its nominal value. It appears as spectral spreading around a carrier and is a key metric of signal… Concept/Framework Phased Array Antenna Phased Array Antenna is an antenna system that steers its beam electronically by controlling the phase of multiple radiating elements, enabling directional beam movement without mechanical structure rotation. Hardware Pointing Accuracy Pointing Accuracy is the degree to which an antenna or sensor is aligned with its intended target direction, measured as the alignment error between actual pointing direction and desired target… Operations Polarization Polarization is the orientation or state of the electric field of a radio wave or electromagnetic signal. It is a property of the signal's field geometry. Concept/Framework Polarization Isolation Polarization Isolation is the degree to which two orthogonal polarization channels remain separated from each other in a radio system. Concept/Framework Power Amplifier Power Amplifier is an amplifier that increases signal power to drive an antenna, transmitter, or other output stage. It provides the drive power for transmission. Hardware Power Subsystem Power Subsystem is the system responsible for generating, storing, regulating, and distributing electrical power within a vehicle or spacecraft. It supplies the electrical loads. Hardware
