System Engineering

Model Based Systems Engineering


Type of project: Semester project / Association / Master thesis Participants: 2 - 4 students Section: STI, Minor in Space Tech or System Eng Description: In this project, you will join the CHESS mission at the end of Phase B, and you will contribute in bringing the mission to the next milestone, the PDR. To achieve this goal, you will need to focus on different tasks, mainly ICDs and Risk Analysis. The interface control documents (ICDs) are key to the CHESS mission. They define how the different components, subsystems of the satellite interact with each other to fulfill the mission’s objectives. The higher level architecture and requirements have been defined (mostly), we now need your help to dive into the specifics. The Risk Analysis identifies the possible failures of the system and it defines strategies to mitigate the causes and effects. Tasks:

  • Familiarize yourself with the mission. As a system engineer it is your responsibility to be very well informed and be able to answer most questions or find the answers.
  • Communicate with members from the other poles and universities to get information on the evolution of the subsystems development.
  • Decompose the problem into manageable tasks.
  • Make relevant design trade offs.
  • Adapt to the situation.
  • Be comfortable not knowing something and keep looking.
  • Update the model of the satellite on Valispace (software) when necessary.
  • Most importantly: be curious and enthusiastic about the work and the association! It will make it that much more fun.
Preferred background courses:
  • Space Technologies minor
  • Spacecraft Design and System Engineering
  • Fundamentals of Systems Engineering
  • Or similar knowledge, system engineering mentality




Testing engineer


Type of project: Semester project / Association Participants: 2 - 3 students Section: STI Description: We are starting to work on real satellite hardware. The Assembly Integration and Testing (AIT) phase is one of the most critical phases of any space project. It is not permitted to have issues with the system once the satellite is launched. A small error may result in a mission failure. The AIT allows to make sure that all the subsystems will work as expected in order to have a successful mission. We should have a first version of our On-Board-Computer, the Power system board and the ADCS module Tasks:

  • Understand the roles and functions of the different subsystems which were bought.
  • Create a list of test procedures which need to be performed on all newly bought subsystems.
  • Test each subsystem individually according to this list.
  • Work together with the Flight Software and OBC team.





Power System

Power system engineer


Type of project: Semester project / Association Participants: 4 students Section: STI Description: After extensive research and simulations on CHESS’s power generation and consumption, a COTS EPS has been selected and should be in our hands by February 2021. Being a vital element to the system, it is important to test the board, the batteries and the solar panel deployment system to make sure everything is well configured and ready to fly. You’ll be in touch with all of the other subsystems to try and simulate their power needs and test if the board and batteries distribute energy correctly and efficiently. Finally an estimation of State of Charge for the batteries should be made to ensure that the system lasts the full 2 years of the Mission. Tasks:

  • Estimate State of Charge of Batteries for Battery monitoring
  • Finalize and Confirm Power simulations
  • Test the Power Distribution Board of the EPS
  • Test the Batteries of on the EPS
  • Discussions and work with the rest of the team to keep the system up to date
Preferred background courses:
  • microcontrollers, electronic basis, coding skills (mainly for programming microcontrollers, C/C++)

Structure

Vibration Analysis


Type of project: Association Participants: 1 students Section: STI Description: During the launch, the satellite withstands loads, vibrations that may use or break the structure. An analysis is carried out to derive the fundamental frequencies of the structure and detect eventual problems Tasks:

  • The aim is to continue the project already done to apply ongoing modifications.
Preferred background and skills ::
  • Ansys software




Building of a mass model


Type of project: Association Participants: 1 - 2 students Section: Any Description: To ensure the CubeSat sustains the launch and life in orbit, we have to verify the structure and the subsystems are capable of resisting a certain amount of vibrations and accelerations. In this context, we would like to build a realistic simplified model of the CubeSat and test this model in vibration. This position offers the opportunity to modify the design and build the mass model. Tasks:

  • Machining/3D printing of a mass model




Thermal Analysis/ Control


Type of project: Semester project / Association Participants: 1 - 2 students Section: STI Description: The temperature of the satellite through its life is a crucial matter that has to be studied, to make sure every component stays in its operability range. An finite element analysis has to be carried out in order to check the thermal behavior and if the requirements are respected. Tasks:

  • A first draft was done on Matlab, a FEM analysis must be done to obtain more precise results.
Preferred background and skills ::
  • Matlab / Ansys





Flight Software

Flight Software development


Type of project: Semester project / Association Participants: 2 students Section: IC, Syscom, MT, Elec, others Description: The subject of this project concerns the development of the satellite's flight software (Flight Software - FSW) whose role is to manage all the interactions between the on-board computer (OBC) and the various subsystems (described above), as well as communication with the ground. An important point is the development of automatic procedures for testing the satellite to ensure that it functions correctly whatever the conditions. Currently several HES-SO students (Master's thesis, semester work) are designing and developing the on-board computer, the FSW, the test methodologies and a simulator to evaluate the functioning of the satellite with sub-systems that are not yet available. Tasks:

  • The aim of the project is to take over the work done, improve it and make it fully functional with all the satellite's real subsystems. The notions of robustness and reliability are very important, test procedures according to the mission specifications must be set up and validated.
  • Part of this work will be done with technologies developed by NASA such as FPrime (https://github.com/nasa/fprime).
Preferred background and skills:
  • As this project involves a lot of people, the candidate will have to work in collaboration with engineers from other schools and other fields.
  • C / C++ / Python





On-Board-Computer (OBC)

Concept of Operations development


Type of project: Semester project / Association Participants: 2 - 4 students Section: STI, Minor in Space Tech Description: The Concept of Operations (CONOPS) is what defines how the satellite will work after the launch at the system level. This is a crucial part of the mission as it states what will be the time sequence of the operations and what to do in case of a failure. The CONOPS has been started the last semesters but it has to be precisely refined in order to be fully operational for the mission. Tasks:

  • Finalizing the CONOPS
  • Implement it in Valispace (MBSE tool)
  • Duty cycles analysis
  • Power, Data, Mass budgets determination
