Abstract
We present methods to automate AUT-probe alignment on a robotic antenna range using iterative fitting methods. Data collected during pose refinement is used to characterize offsets to the robot motion frame and the end effector measurement frame with minimal additional information. The fitted offsets are then used to solve the inverse kinematics problem to align the antennas. We detail variations of the approach that use external or controller integrated kinematic models. Experimental alignments for a 3-pair antenna measurement were performed on the LAPS antenna range with this technique, resulting in 7.59 um RMS position error and 40.7 urad RMS rotation error.Proceedings Title
