BME Suborbitals: Avionics System Development

Driving the Future of Sustainable Mobility with Eurocircuits

BME Suborbitals is Hungary's first and largest university rocketry competition team. It is the competition team of the Budapest University of Technology and Economics, currently operating with around 80 active members. Our team is organized into 8 working groups, so everyone contributes to rocket development according to their own field of expertise.

This year, our team successfully qualified for the European Rocketry Challenge, Europe's largest student rocketry competition. With our competition rocket this year, Aurora, our goal is to achieve the best possible performance, which requires a reliable and stable avionics system. EuroCircuits provided significant support in creating this system by manufacturing the necessary printed circuit boards that supported our work.

The various printed circuit boards play a key role in the operation of our rocket:
The Backplane is the central connection point of the avionics subsystem. Its task is to distribute power and communication signals between the modules. It also provides mechanical anchoring for other subsystems.

The Telemetry Computer ensures communication between the rocket and the ground station. This unit transmits the most important flight data in real time. To implement the system, we needed precisely impedance-matched traces and circuits operating with the lowest possible noise. Here, the manufacturing precision provided by EuroCircuits played a key role.

The RF Power Splitter PCBs enabled us to use patch antennas inside the rocket.

The Camera Piggyback Boards are responsible for operating the onboard cameras. Thanks to them, the cameras not only capture spectacular footage but also provide valuable data for post-flight analysis.

The reliability and performance of the avionics system largely depend on the quality of the hardware, which is why EuroCircuits' support was so essential for us.

We would like to thank EuroCircuits for their support. Without their help, we could not have realized our ideas at such a high standard. We are grateful that they contributed to the advancement of Hungarian rocket development and to showcasing the knowledge and innovation of Hungarian engineering students on the international internship.
