From the project

Sensing hardware and software

Repository for all Olin Rocketry hardware and firmware.

The purpose of the avionics system is to determine when to deploy the drogue and main chutes, and to send the signal to do so to the recovery system. The flight computer contains several sensors to help detect apogee, and a microcontroller to read and process the data and send the signal.

- a commercial-off-the-shelf (COTS) flight computer; - a student-designed flight computer, which includes sensors, microcontroller, GPS, and radio; and - a student-designed battery management system (BMS).
