SYSTEM AND METHOD FOR IMPROVED POINTING ACCURACY

摘要

A system and method for controlling the power of a transmitter helps to ensure that the transmitted signal is within the dynamic range of the intended receiver. The transmitted signal is received by the receiver. The received signal strength is measured to determine its power level in relation to the dynamic range of the receiver. Where the signal strength is too high, the transmitter is slewed to effectively decrease its pointing accuracy, thereby causing a lower-power portion of the transmitted signal to impinge upon the receiver. Similarly, where the signal strength falls below a desired level, the transmitter is slewed back toward the center-pointing position, effectively increasing its pointing accuracy, and thereby increasing the signal strength received at the receiver.
