Abstract: A system for active co-boresight measurement includes a detector, first and second steering mirrors, and a controller. The detector detects a portion of a transmission beam emitted by a transmitter and a portion of a received beam received from a remote terminal. The controller instructs the first steering mirror to scan the detected portion of the received beam to determine an alignment position. The controller controls a position of the first steering mirror to align the portion of the received beam with the alignment position on the detector, and controls a position of the second steering mirror to align the detected portion of the transmission beam with a defined position on the detector. The detected portion of the received beam at the alignment position and the detected portion of the transmission beam at the defined position correspond to the received beam and the transmission beam being aligned.

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.
