This work focuses on the integration of a constellation of CubeSats for high-energy astrophysics.
HERMES-SP (High Energy Rapid Modular Ensemble of Satellites – Scientific Pathfinder) is a mission concept based on a constellation of nano-satellites in low Earth orbit (LEO). These satellites host new miniaturized detectors designed to investigate the X-ray temporal emission of bright high-energy transients such as Gamma-Ray Bursts (GRB) and the electromagnetic counterparts of Gravitational Wave Events (GWE). All the details about the mission and the science involved can be found on the official website of the project:

As a payload engineer, my main contribution involved the integration of the detector block of the satellites, known as the scientific payload (SP). In addition to the actual assembly and integration of the satellite hardware, I was responsible for various activities necessary for the final integration. These activities included:
- Developing procedures for different stages of the integration process, component manufacturing, testing, etc.
- Designing and producing auxiliary mechanics required for each step of the integration (jigs, supports, protections, etc.)
- Components design and manufacturing
- Designing and experimentally verifying multiple solutions involved in the integration
- Testing components and assemblies at different stages of the integration
In addition to my primary role, I also participated in electronic and mechanical design work, providing assistance in developing reliable and robust solutions.
The work on the satellites is ongoing, but to date, seven payloads have been successfully completed and shipped for the next assembly steps.
