Abstract
As advances in space technology, much effort has been devoted to the field of microsatellite, due to its cost-effectiveness for conducting various space mission. The present article investigates design and verification of electrical power subsystem (EPS) for the SSS-1 platform, which is a student small satellite proposed by Beihang University, Beijing, China. EPS consists of three units, including solar array (SA), battery pack unit (BPU), and power control and distribution unit (PCDU). Their main design indexes and the preliminary design results are first briefed. Due to the energy shortage arose from energy balance analysis, an optimisation design of the EPS has been adopted, involving optimisation of the SA layouts as well as low battery level warning for on-board computer. Besides, the EPS is modelled via MATLAB®/Simulink® combined with orbit simulation. The verification modelling results manifest that ultimate design of EPS is capable of sustaining the energy consumption of SSS-1, and thus associated energy balance can be attained.
