Abstract:
A compact system for active co-boresight measurement includes a detector, a steering mirror, and a controller. The detector detects a portion of a transmission beam emitted by a transceiver and a portion of a received beam that is received from a remote terminal. The controller measures an offset between the detected portion of the received beam and the detected portion of the transmission beam. The controller controls a position of the steering mirror to align the portion of the received beam with a defined position on the detector, the defined position based in part on the offset.
