A balloon borne stabilized platform has been developed for a remotely operated altitude-azimuth pointing of a millimeter wave telescope system. A modeling and controller design of the azimuth point system of the platform is presented. Simulation results show that the system is capable of continuous operation with pointing rms to better than 0.01 deg. Ground testing results show continuous operation with pointing rms to better than 0.02 deg; while results of the first flight from the National Scientific Balloon Facility (NSBF) at Palestine, Texas show pointing rms better than 0.02 deg.
