The modular segmented space telescope can get rid of the limitation of the effective envelope of the fairing of the existing launch vehicle, meet the requirement of the large aperture of the space telescope, and play an important role in space exploration and earth observation. In order to solve the problem of power supply and signal transmission of the primary mirror of the segmented space telescope, a kind of modularization space telescope primary mirror system for in-space assembly is first proposed in this paper. Then, according to the index requirements and the assembly process of primary mirror, the wireless energy and signal transmission scheme and system structure are proposed. By analyzing the key parameters, the optimal system of wireless energy and signal transmission on the segmented mirror is achieved. The proposed system realizes high power and high efficiency transmission of power supply energy and reliable transmission of data signal during and after assembly of the segmented mirror, and solves wire connection problems caused by the traditional wired transmission mode.
