Abstract: The performance of an autopilot controller has been an issue for industries over these days as they make use of less effective microcontroller. This limitation can be overcome by using FreeRTOS based implementation logic and by replacing less effective microcontroller with STM32 microcontroller. The prime objective of this paper is the development of FreeRTOS based autopilot controller using STM32.this autopilot controller comprises of Global Positioning System (GPS), Sensor Suite, external flash for data logging, Servo motor to control aileron, rudder and elevator action and MAVLink based transceiver in order to communicate between Micro Aerial Vehicle (MAV) and Ground Control station (GCS).this system focuses not only on device monitoring but also controlling it. The GCS comprises of Mission Planer software which is used to monitor the data received from MAV and can also control the flight mode from it. The Radio Frequency (RF) joystick is used for MAV’s flight control.
