We describe the development and implementation of a light-weight, fullyautonomous 2-axis pointing and stabilization system designed for balloon-borneastronomical payloads. The system is developed using off-the-shelf componentssuch as Arduino Uno controller, HMC 5883L magnetometer, MPU-9150 InertialMeasurement Unit (IMU) and iWave GPS receiver unit. It is a compact and ruggedsystem which can also be used to take images/video in a moving vehicle, or inareal photography. The system performance is evaluated from the ground, as wellas in conditions simulated to imitate the actual flight by using a tetheredlaunch.
