    Robust Self-Calibration of Subreflector Actuators Under Noise and Limited Workspace Conditions by Guljaina Kazezkhan, Na Wang, Qian Xu, Shangmin Lin, Hui Wang, Fei Xue, Feilong He, Xiaoman Cao

    Published 2025-06-01

    Accurate kinematic calibration of subreflector actuators is essential for pointing precision of large radio telescopes, particularly at high frequencies. Conventional least-squares methods are vulnerable to noise and outliers, and their accuracy may degrade when limited pose diversity leads to poor...
