Query: Pointing System for the Balloon-Borne Astronomical Payloads   We describe the development and implementation of a light-weight, fully
autonomous 2-axis pointing and stabilization system designed for balloon-borne
astronomical payloads. The system is developed using off-the-shelf components
such as Arduino Uno controller, HMC 5883L magnetometer, MPU-9150 Inertial
Measurement Unit (IMU) and iWave GPS receiver unit. It is a compact and rugged
system which can also be used to take images/video in a moving vehicle, or in
areal photography. The system performance is evaluated from the ground, as well
as in conditions simulated to imitate the actual flight by using a tethered
launch.
