Our expertise spans across key space engineering domains — from thermal and RF design to resilient electronics and system integration. Below is an overview of our core competencies.
We also have a strong network of contacts and potential collaborators, allowing us to support projects requiring greater capacity — depending on the complexity of the project.
We draw on many years of hands-on experience across the space and aerospace industries, as well as from specialized fields in academia and fundamental research. This unique background allows us to bridge the gap between cutting-edge theory and real-world engineering.
Martin is a specialist in thermal and radiation engineering with a background in space missions. He focuses on environmental simulations, radiation shielding strategies, and ensuring system reliability in harsh space conditions.
Petr brings expertise in RF engineering and satellite communications. His work includes antenna design, link budgeting, and integration of high-performance communication systems into spacecraft platforms.
Tomáš is a hardware and FPGA engineer with experience in the design of robust embedded systems for space. He specializes in low-power, radiation-tolerant architectures and onboard processing using FPGAs.
The following references represent projects our team members have contributed to throughout their professional careers — including work carried out prior to founding Epsilon Labs, during engagements with other companies, or as independent consultants. We've gained invaluable experience through hands-on involvement in demanding space projects — from design to validation and delivery. We’ve successfully contributed to numerous missions and studies, covering everything from subsystem prototypes to mission-critical components for leading space agencies and private partners.
In this project, we designed the communication architecture for the entire mission and conducted a thermal analysis of the satellite based on preliminary subsystem definitions and internal layout. We have evaluated the influence of Lunar dust on the orbit. Tools used: Thermica, Ansys STK, Ansys HFSS
From the perspective of provided expertise, the scope was similar to the LUMI project — encompassing both communication architecture and thermal analysis.
The third and, for now, final project where we provided our expertise in a similar setup.
As part of this mission, we contributed in the areas of thermal analysis, electrical subsystem integration, EMC testing, co-development of proprietary subsystems, and addressing communication aspects – including link budget, ITU service registration and coordination, RF section integration, and testing within our own SDR-based modules. We have also performered radiation analysis to estimate the total ionizing dose on the orbit
