A balloon‐born stabilized platform has been developed for the remotely operated altitude‐azimuth pointing of a millimetre wave telescope system. This paper presents a development and implementation of model reference adaptive control (MRAC) for the azimuth‐pointing system of the stabilized platform. The primary goal of the controller is to achieve pointing RMS better than 0.1°. Simulation results indicate that MRAC can achieve pointing RMS better than 0.01°. Ground test results show pointing RMS better than 0.03°. Data from the first flight at the National Scientific Balloon Facility (NSBF), Palestine, TX show pointing RMS better than 0.02°.
