- Development of a CubeSat power management subsystem for the ALSat#1 MissionPublication . Panagopoulos, Jorge Antunes; Guerman, Anna; Zazzera, Franco BernelliThis thesis aims to develop and analyse the power management subsystem for the ALSat#1 mission that studies the cosmic rays in low earth orbit. The primary task is to find components to build and make the CubeSat able to do the mission and subsequently analyse if it is capable to make the mission in three different orbits RAANs (RAAN 0º; RAAN 53.5º; RAAN 90º) with different eclipse times. This was done by using a MATLAB programme to analyse the energy consumed and energy deficit during an orbit and during a day. It was found out that the options orbit with RAAN 0º and orbit with RAAN 53.5º can complete the mission without change. However, the orbit with RAAN 90º has some deficit cumulated after a day which leads to energy insufficiency, and is only possible to overcame it with some changes in the algorithm or in the components used.
