This study focuses on the influence of the monitoring method and control complexity on the opera-tor performance in manually controlled spacecraft rendezvous and docking (RVD). Two one-factor experi-ments were designed on a simulated RVD system. One examined the video guidance and periscope moni-toring methods, and the other examined three control complexity levels using one-axis RVD control, two-axis RVD control, and three-axis RVD control. Eighteen male volunteers aged 22-35 participated in the ex-periments. The results show that the RVD operating time increases with control complexity. Based on the operators’ findings, the two-axis control is the easiest. The monitoring method has no significant influence on failure rate with the low complexity using one-axis RVD control.
