Abstract:Remote sensing cubesat is in the transformation stage from technical test to business application, how to alleviate the energy limitation and obtain higher solar charging efficiency is important to the development of constellation construction. By designing the solar wings of cubsat with different configurations, and Constructing the simulation model of solar array, the charging performance, efficiency and service performance of different configurations of solar wings in microgravity space are simulated and analyzed. The results show that selecting the optimal configuration of solar array can provide better energy and power support for remote sensing cubesat, it provides an effective reference for the follow-up remote sensing cubesat to carry out more commercial applications.
