Abstract
In the space mission, gathering as much as possible of the dynamics data is required in order to reduce any risks. However, in general,spacecrafts do not have enough sensors because of the strict limitations of electricity, weight, and communication. Therefore, the estimation of the unmeasurable data is important. In this paper, the HTV (H-II Transfer Vehicle) capture mission with the SSRMS (Space Station Remote Manipulator System) is analyzed. Using the telemetry data from HTV and video from ISS camera, the HTV-SSRMS relative motion and contact force are estimated.
