  Your Role

CubeSats are proposed for forming satellite networks. Satellite networks are increasingly popular for missions requiring wide-area coverage, such as gravity mapping, wildfire tracking, or improved spatial and temporal resolution for threat-detection capabilities. For these applications, enabling satellites in the network to communicate by introducing intersatellite link capabilities would have benefits such as persistent connection, or reducing the waiting time for satellites to be in the range of a ground station, resulting in faster transfer speeds, higher bandwidth, and lower latency, enhancing time-sensitive data operations. Currently, the preferred technology for intersatellite links (ISL) is optical communication (in particular laser-based), due to its higher speed and data transfer capacity, higher modulation bandwidth and smaller and lighter antennas, in comparison to traditional radio frequency (RF) and microwave systems. Moreover, unlike RF and microwave technologies, laser intersatellite links (L-ISL) do not require spectrum licensing or frequency coordination, as the point-to-point laser signal is safe from interference. Advancements in L-ISL technology enabled the development of terminals with reduced size, weight, and power requirements to the degree that they can be integrated into kg-sized satellites. Miniaturized L-ISL terminals are an enabling technology for numerous space applications with numerous benefits such as shorter time-to-market (or time-to-science) and lower cost, reducing or eliminating the use of extensive ground-based relay systems and tracking systems, formation flying for high-quality data and services, increased temporal resolution and revisit rate, and unprecedented satellite missions such as opportunistic (on-demand, fast to deploy and decommission) missions for weather and agricultural data collection, disaster monitoring, or other forms of Earth observation.

The objective of this PhD thesis is to develop the system architecture and prototype of a miniaturized L-ISL communication terminal for 1U or smaller (subnano) satellites.

The planned research will explore how small a L-ISL terminal can be made to serve in a satellite network, how that network would look like and how it would serve various mission objectives.

A major outcome of this project is a prototype L-ISL terminal for subnano satellites ready to be tested in orbit in a technology demonstration mission. We will address this objective by conducting the following work:

• Benchmarking, use cases and function model generation
• Laser intersatellite link design exploration and conceptual design
• Model-based Systems Engineering design of laser intersatellite link terminal and mission
• Intersatellite link terminal prototyping and evaluation
• Manufacturing, verification and potentially launch

  Your Profile

Experience: The ideal candidate should have some knowledge and experience in some of the following topics:

• Hands-on experience with the design of electronic components and small spacecraft, e.g. CubeSats, PocketQubes, etc.
• Experience with spacecraft communication (ideally optical)
• Systems engineering: Processes, methods, tools for developing complex systems
• Model-Based Systems Engineering
• Fundamentals of astronautics

You should have the following aptitudes:

• Like to “build things”
• Pragmatic and hands-on
• Systems thinking: Holistic thinking, keeping the “big picture” in mind
• Team player

The position holder will be required to perform the following tasks:

• Carrying out research in the predefined areas
• Carrying out lab activities and maintenance in collaboration with other team members
• Disseminating results through scientific publications
• Assisting in the organization of relevant workshops

Qualification: The candidate should possess an MSc degree or equivalent in Engineering, Computer Science, Applied Mathematics or affine.

Programming Skills: Experience with programming spacecraft software or other embedded systems is an asset. Experience with Matlab, LabView, or another programming language is an asset.

Design tools: Experience with Eagle or other PCB design software is an asset. CAD software experience is also an asset.

Systems Engineering Tools: Experience with one or more MBSE tools (Cameo, MagicDraw, Capella, etc.) is an asset.

Language Skills: Fluent written and verbal communication skills in English are required.
