Abstract
An apparatus for simultaneous calibration and communication of active arrays of a satellite may include a base transmitter, a satellite receiver, a satellite transmitter, a base receiver, and at least one computer. The apparatus may simultaneously transmit and receive a calibration carrier and a communication carrier at different frequencies in order to calibrate the apparatus using the calibration carrier without interrupting the communication carrier. The use of different frequencies may avoid interference between the calibration and communication carriers.
