consider the possibility of oshoring the protection circuit of the batteries on one electronic card and, in this case, the card with least components is the xEPS. The last two cards are managed by the student in charge of EPS and xEPS subsystems. • Finally, the Telecommunication (COM) card is placed on the top of the satellite, close to the end plate. This card is managed by students in charge of the COM subsystem ([28] and [29]). Schematics and exact dimensions of each of these cards are available in appendix B, such as the available volume for each of them. Each of the components presented in this section, is separated from the others by spacers, made of Al − 6061 T 6, with variable dimensions (4 mm, 15 mm and 19 mm). The whole is xed to the main structure with the help of 4 M3 × 8 cm stainless steel endless screws, which are screwed on the base plate. On the other end of these screws, there are four midplane standos [30], made of Al −6061 T 6, that allow to connect the screws to the chassis. These midplane standos are also xed using M3 nuts. Schematics and pictures of these xations are available in appendix C. Pictures of the engineering models of each of these cards are available in Figure 2.19.
