On-orbit service is one of the main developing trends of future satellites, where on-orbit software reconfiguration and hardware assembly are the key technologies. In this paper, combined with the electromagnetic technology and "pen cap" docking mechanism, an autonomous rendezvous and docking control mechanism with 1U dimension was designed to be used in the cubesat field. And based on the designed electromagnetic docking mechanism, the comparison between precise model and distant field model of electromagnetic force and moment was conducted, and the application range for distant field model with docking distance more than 0.1 m was gained. Using simulation analysis method, it is found that the ratio of without iron core and with iron core is in the range of 10-8~10-4, which provides reference for distant field model correction.
