Master Thesis - OUFTI-1

these ones, an estimation of the mass was presented in a "best case/worst case" philosophy.
The mass budget nally obtained is presented in Table 2.2. It is rstly divided between
the several subsystems in order to focus on the weight of each component to identify the
main mass consuming ones. Then, a general table is presented and the total mass of
OUFTI-1 is calculated. It should be noted that each mass was rounded to upper 0.01 g,
which brings some safety to the measurements. However, to obtain a reliable nal result,
a Safety Factor (SF) of 2% was applied to the total mass of OUFTI-1.
2.6 Summary
Through this chapter, the general conguration of OUFTI-1 was discussed.
First, a reference frame was dened to allow to locate precisely each component of the
CubeSat. The advantages of the selected frame were also highlighted.
Then, the organization of the several subsystems was exposed. For each of them, a
detailed description of the location, xing methods and general physical and mechanical
properties was presented. These descriptions allow to bring an overall view of the satellite
to the profane.
Finally, the physical properties of OUFTI-1 were determined, and their fulllments of
the ESA requirements were veried.
