Mission Design for the CubeSat OUFTI-1

CHAPTER 8Figure 8.5: Total power produced: simulation over one year orbit.Anyway, we are more interested in the power that we can effectively use at eachtime: we calculated therefore the integrated power shown in figure 8.6. To haveit, we integrate the power over each orbit to have the total energy availableand then we divided it by the orbit duration. In this way, we know exactly thepower that we can guarantee continuously to our payload. All the losses on theelectrical power system and in the battery haven’t been taken into account yet.Figure 8.6: Integrated power: simulation over one year orbitWe can see that, even in the worst period of the year, we can guarantee 1.3W. This is the value we will use to dimension our communication system.Galli Stefania 80 University of Liège
