Functional Requirements and System Design Constraints Functional Requirement Design Constraint(s) Power level to be transmitted Availability of prime power, power density in beam Distance of transmission Location of PRS transmitter, receiver and satellite Allowable aperture sizes. Dictated by the available real estate of space for transmitter and receiver apertures and acceptable power densities. Transmission path qualities Attenuation and defocusing effects Beam width control Tolerances on transmitting and reflector surfaces. Beam power density Peak power densities in beam, personnel safety, power density at the edge of the beam, fence lines for access control, safety and health effects, effects on biota. Available technology Source technology, receiver technology, ability to adapt or compensate for transmission medium. Transmitter/Receiver site for Power Relay Satellite applications Latitude and longitude effects on beam transmission. Orbit maintenance for PRS. Radiation pressure on PRS from sun and power beam. Frequency selection. Effects on sizing, system efficiency, all weather operation, rectenna technology availability and efficiency.
