Olin Rocketry is a student-led team with the goal of developing a solid-propellant rocket.
As the lead avionics engineer, I directed a 5-person team in the development of a full-featured avionics suite for the rocket. The system requirements for the avionics include apogee detection, dual parachute deployment, data logging, and telemetry streaming. My concept for the system was centered around modularity in order to provide the team with a future-proof and adaptable avionics architecture.
The Primary Recovery, Instrumentation, and Sensing Module (PRISM) is a pair of PCBs that serve as a standalone flight computer. The PRISM-IO board houses the power distribution circut, mechanical bolt-switches, and two pyrogenic ignitor circuts. The PRISM-FC board features a Teensy 4.1 microcontroller, barometric altimeter, and 9-axis IMU and runs a Kalman filter for vehicle state estimation.
