Avionics

The Omega was the first in house developed flight computer by Delta. It is a high-quality PCB with lots of components. It has 3 pyro channels for deploying parachutes and lighting a second stage motor, a bright RGB LED, two servo outputs for thrust vector control, data logging, altitude measurements, a buzzer to safety arm the rocket on the ground, and a gyroscope for measuring angular acceleration. The gyro values are then filtered multiple times from raw data to radians then to degrees. Then, the computer runs a PID loop to estimate at what angle to gimbal the motor. Once all the math is done it sends the output values to two high quality 9g servos.
