From the project
Full Hardware and Electronics design, Bare-metal GNC flight software for an actively attitude-controlled high-power rocket
Custom STM32H743 flight computer and GNC software for a roll-rate-stabilised high-power rocket.
This is an engineering project, not a product. The safety case, regulatory compliance, and airworthiness of any vehicle built from this material are the builder's sole responsibility.
The project is designed to: - Provide a modular active roll-rate damping system suitable for a wide range of high-power rockets. - Improve flight data quality by reducing excessive vehicle roll. - Improve parachute deployment reliability by limiting roll-induced line twist. - Provide a reusable avionics platform for…
