The research and Development (R&D) Team is going to be a new subsection of the Electric Power Subsystem (EPS), devoted to the design and construction of electronic components related to the EPS team and also other teams.
In Phase 0 and A, the EPS team worked on defining the high-level architecture of the system and the approach for the design of the components, which is to buy fundamental commercial pieces (triple-junction solar cells, Li-Ion off the shelf batteries) to then integrate into in-house designed circuits.
This approach allows high flexibility and a design tailored to the peculiar needs of the mission, while strongly reducing the costs.
To this aim, the team needs to involve two more people, to help in the design and production of the boards.
As PCB Design and Payload Integration Engineer you will be tasked with the development of printed circuit boards that handle the power distribution for the CubeSat.
Based on the requirements from other subsystems the required hardware will have to be chosen and integrated. This will include component selection and matching for compatibility with a focus on
COTS components wherever possible.
The circuits also must be designed to withstand the
environment of space, so careful selection and design is of utmost importance. The PCBs will be designed in CAD and evaluated for performance through simulations.
Finally, the PCB fabrication will have to be outsourced, after which quality control and equipping will be performed by the team.
You will also be in close contact with the other subsystems and payload providers and communicate their requirements to the EPS team.
Roadmap of your activities:
At this point in time, the payloads have been selected and the mission defined. Your job will start with getting familiar with payload and mission requirements by review of the documentation and
literature. Then, you will evaluate how the requirements can be satisfied.
For this purpose, you will have to design PCBs for Power Conditioning and Distribution, the Payloads and the subsystems.
The main task, however, is to guarantee the power distribution is capable of meeting the power and data requirements set by payload and mission.
For this purpose, you will also design and integrate measurement circuits. You will also be in close contact with the other subsystems and payload providers, such as Cambridge University, and communicate their requirements to the EPS team.
* Please note that due to Covid-19 pandemic the job can be carried on remotely
- Identify suitable technologies that may be able to meet the sub-system requirements.
- Carry out research on the state of the art in circuit design for space applications and implement it accordingly
- Collaborate with team members to ensure that the overall design works properly.
- Ensure good documentation is maintained, for smooth hand-over after graduation/resignation.
- Full-time registered bachelor, master or PHD student at Politecnico di Milano – any department (preferably Electronic Engineering).
- Commitment to dedicate about 7 hours a week on average. Available to be with PoliSpace for at least 6 months after joining.
- Good understanding of electronic circuitry and architecture.
- Excellent knowledge of electronic circuit design principles
- Experience with Matlab and LTSpice or other simulation software
- Some knowledge of EAGLE or other PCB design software
- Excellent technical writing and editing skills (LaTex, Microsoft Office, etc)
- Hands-on experience in hobby-level electronics assembly is a plus (drones, RC Cars, etc.)
- Must work well in an international environment.
Solid time management skills: team members will be responsible for important tasks that are critical to the success of the mission. Failure to deliver on time will delay the project.
- Punctuality at meetings is also crucial.
- A sense of drive should be apparent from your application (letter, cv, interview): The project will be difficult and it is necessary to remain devoted throughout its course.
- Must be an autonomous worker. If you are given a task it is expected that you complete it without constant supervision.
- Must be a quick learner. There will be a lot of firsts for everyone in this project so the team members need to be adaptive. It’s important that you can read new concepts, understand them and apply them quickly.
