Scientific paper

A small telescope control system was developed for balloon-borne far-infrared scanning observations with medium angular resolution. The stabilization of a balloon gondola was performed by a reaction wheel-based servo-mechanical system driven by a torque motor, realizing pointing accuracy better than 0.1. The method employed in this system is unique in that only the internal frame which the telescope is attached to is stabilized around a vertical axis of the gondola, while the outer gondola is being oriented separately by the so-called twist-rewinding servosystem. The performance of the whole system is presented including the three-color far-infrared photometer actually used in the last observation.
