Based on the requirements of rapid and low cost construction for large-scale satellite constellation construction, combined with the characteristics of high-speed, small size and low power consumption of space laser communication, satellite to ground and satellite to satellite full link laser communication constellation is designed, the communication system and wavelength were analyzed and selected, and key technologies for space-based laser transmission were proposed to address issues such as weather impact, rapid acquisition, and high-precision pointing in satellite to ground laser link communication, providing reference for large-scale satellite constellation design.
Aiming at the envelope constraint problem of carrier rocket fairing, based on the design idea of on orbit assembly and maintenance, in this paper a general design scheme of a remote sensing large-platform satellite (RSLPS) that can realize large scale multi-load collaborative observation is proposed. The basic process of on orbit assembly is introduced, and the composition, structural form and technical principle of the universal interface design, micro vibration control design and thermal deformation control design of the load platform are expounded. The proposed design scheme provides a valuable choice for the research of RSLPS based on on orbit assembly and maintenance.
