STM32 based Flight controller simulator for satellites
The Flight Computer (FC), interfaces with sensors and actuators to perform attitude determination and control. Sensors like
- Magnetometer – Measures current pointing based on earths magnetic field
- Inertial Measurement Unit (IMU) – basically a gyroscope
- Fine Sun Sensors (FSS) – detects general direction of the sun
- Star Trackers (ST) – Uses image of the stars to determine direction that spacecraft is pointing
- Global Positioning System (GPS) – gets position and velocity
Actuators:
- Reaction Wheels (RWA) – Spins a wheel to change attitude
- Magnetorquers (EMT/MTQ) – Magnets that interact with earth’s magnetic field to change attitude
The project involved writing simulator code (c++) in FreeRTOS to test above sensors and actuators and other flight controls
