EGSE - Wiring and Setup

The main objective of this section is to document and explain how to proceed with the wiring of the different parts of the EGSE to use it correctly. Additionally, it will explain the fundamentals for operating it properly.

The EGSE does not have all the SSVs interconnected by default, so we will need to create cable buses to interconnect the SSVs, we also need to prepare some special pieces to hold certain parts, such as the solar panels and the bottom board with the kill switches.

Next, we can see an render of the EGSE without connections and without any SSVs. Therefore, we will proceed with documenting the necessary interconnections for the EGSE and the properties it offers

Cable bus

First, we need to prepare the interconnection buses, so we will start by creating these using mainly PicoBlade and PicoClasp connectors (Before making the cables, we will need to ensure they have the correct length)

The +Y magnetometer with the ADCS has to be connected through a simple wire; there is no connector between these parts.

Each cable should be approximately the length specified in the table, which serves as a reference for the cable lengths used in the poCat-LEKTRON EGSE.

In this following diagram, we see the cables we just constructed indicated by black lines. These lines represent which parts of the EGSE will be wired. The colors indicate that they belong to the same part.

If we look closely, all the colored areas are not connected by default; we connect them using the cables we just made
